Serve fruit for dessert. Top pasta with leftovers - cooked vegetables, ground meat, chicken, or even a small amount of vegetable soup. Or combine with a low-fat salad dressings or spoonful yogurt. Use fruit to balance spicy dishes. Tropical fruits like mangoes and pineapple temper hot flavors, and balance and brighten, as well.
Apples work well with curries, and bananas add a delicious counterpoint to hot chile peppers.
Think texture as well as flavor. Add a toss of toasted pine nuts or toasted chopped walnuts to a creamy pasta sauce for added interest. Don't be afraid to substitute ingredients. If you plan to use zucchini in a pasta sauce, but the eggplant looks particularly good, substitute the eggplant. Double your favorite recipes, and freeze the extra servings for later use.
