Make recipe as above, or let kids choose their own DIY ingredients from the following lists: protein (instead of ground beef, try ground turkey, shredded chicken, crumbled tofu or beans); whole grains (instead of tortillas chips try cooked brown or white rice or cooked quinoa); vegetables (instead of lettuce and tomatoes choose chopped sweet bell peppers, chopped cucumber, cooked corn kernels and/or chopped jicama); toppings (instead of cheese and avocado choose Greek yogurt, chopped black olives, ranch dressing, pepitas or salsa).
