Avocado

I often wonder if tostadas—crisp tortillas mounded with your choice of topping—were the first version of modern-day nachos. If so, these would definitely be called "supreme." Crunchy tortillas are layered with slices of creamy avocado and topped with a zesty crab salad to make the perfect appetizer.

Avocado pureed with buttermilk (low-fat) and yogurt (with the cream on top) yields a pale green soup laced with masses of minced herbs, textured with cucumber, and garnished with slivered radishes, herbs, and green pistachios. All in all, it's a fine soup for a hot day, and although the recipe makes just a scant quart, it will be enough for four or more servings.

At the Citymeals-on-Wheels event, our food editors were astonished by the variety of flavors layered in these summer rolls. Within the confines of each wrapper, chef Alfred Portale combined sweet crabmeat, crunchy tobiko (flying-fish roe), and creamy avocado, then finished it with a citrusy yuzu sauce.

A classic American sandwich gets a makeover: The avocado dressing has an inviting creaminess to it, and the crunchy grilled croutons are a revelation.

Marinating the fish in lemon and lime juices "cooks" it while it sits in the fridge. Don't leave the fish in the marinade longer than six hours or it may become tough. Serve the tacos with corn and black bean salsa and offer chocolate mousse spiked with a little chile powder for dessert.

Colombia may be the best kept barbecue secret in South America. Sure, Argentina gets the attention for its cowboy-style asado. And Brazil has enjoyed spectacular success exporting its rodizio-style restaurants—the kind where the waiters parade spits of grilled meats through the dining room. But Colombia? I doubt that most North Americans could name a single Colombian grilled dish. Well, it's time to shine the spotlight on the only country in South America to have coasts on both the Atlantic and the Pacific, whose cool-weather ranching district produces well-marbled, full-flavored beef, whose grill masters make extensive use of marinades (unlike the simplicity prized by their Argentine counterparts), and whose mastery of the art of grilling on charcoal extends to some unique techniques. Here's a not-so simple flank steak redolent of cumin, green onions, and beer.

his Colombian version of guacamole is smoother than most Mexican guacamoles, and it's used as a sauce for grilled meats, not just as a dip for tortilla chips.

Unless you're shopping for "meatloaf mix," it's easy to overlook ground pork. Smoky pork burgers topped with melted Muenster and creamy avocado will broaden your horizons. Don't skip the sliced tomatillo—its crisp tartness really perks things up.

Grilled avocado is one of those things that sound faintly ridiculous until you try it—then you wonder why you never had it before.

In this impressive main course, sautéed scallops and shrimp are paired with a vibrant sweet-savory salsa. Serve the seafood and the side dishes with warm corn or flour tortillas.

Tinga de Puerco Pork shoulder is a humble cut of meat, but it packs a lot of flavor. Here it is simmered with a chipotle-spiked tomato sauce to make a smoky-spicy topping for crisp little tortilla chips. They can be served on a plate as a first course or passed on a tray as a nibble with cocktails or beer. Tinga is also very good as a filling for warm corn smoked Spanish sausage.

Poblanos Rellenos con Papas y Aguacate What a wonderful dish this is, full of unexpected flavors and textures. Roasted poblano chiles are stuffed with mashed potatoes and avocados, then marinated in a sweet-and-sour mixture seasoned with roasted garlic.

I really love this soup. The flavors will remind you of corn chowder, but the texture is much lighter. The soup is bright and fresh and can be made year-round since it tastes just as good when using frozen corn as it does when using fresh.

Ensalada de Nopales Do not be afraid of this salad. Nopales (cactus leaves) are quite delicious and may remind you of green beans or okra. In fact, you could make this salad with green beans perfectly well. But do try the nopales if you never have—you may discover a new favorite vegetable. You will find canned nopales at Latino markets, but fresh ones are much better.

Be anything but crabby after enjoying this sunny citrus bisque. You'll net half your daily folate needs per bowl.

These roll-ups are great for school and burst with tuna and veggies. If your child likes wasabi's heat, add an extra 1/4 teaspoon to the tuna mixture.

If the idea of tomatoes and watermelon together sounds odd to you, this dish will be a revelation. There is a saying that what grows together goes together, and in this case it is true. If you think of tomatoes as a fruit, which they are botanically, this combination makes more sense. Seasonality, however, is the key. I make this salad only in the summer, when tomatoes, watermelon, and cucumbers are at their peak of flavor. Rich, creamy Hass avocadoes are included to lend a nice contrast of flavor and texture. I always toss this salad together before serving, but for the photo opposite I was inspired to create a painstaking mosaic of the ingredients. If you're so inclined, feel free, but don't say I didn't warn you—it takes a lot of time.
