When my twins were two years old I was working evenings. They loved pasta and cheese and it was easy for my hubby to fix. But by itself it is not too healthy. I devised a series of recipes based on a box (or two) of Shells and Cheese and various cans of food. The shells and cheese called for in these recipes are the kind with the cheese sauce, not the powder kind. Remember this is a mac and cheese dish not real paella made with rice and without cheese.
