One of the Default Dinners is Mexican night.
More often than not, lately we have been doing tacos. I have a recipe from a recent issue of vegetarian times that I use the most. Basically you make a bean filling out of beans, tomatoes and onions and then add lots of toppings like : avocado, lettuce, tomato, roasted peppers and onions, cheese (for those eating dairy).
My kids love these because they get to choose their own toppings. I was excited to discover that the taco shells I already buy are gluten-free.
