Fajitas are a fun way to allow children some choice in putting together their meals. Consider adding chicken, beef or shrimp to the marinade for variety. Other spring and summer vegetables like asparagus, squash, or eggplant are also excellent choices for this recipe. Sauté the vegetables the night before, reheat in the morning and send them to school in a thermos with the toppings like cheese and guacamole on the side (see Guacamole with Baked Tortilla Chips recipe). Bigger kids will love assembling their own fajitas at lunchtime.
