Cup-A-Lasagna

The amounts in this recipe depend upon the size of your thermos. Just keep layering until the thermos is full!

Whole grain flour tortillas
Tomato sauce
Grated cheese (mozzarella, cheddar or soy cheese)
Grated Parmesan
Ricotta cheese
Chopped raw spinach

Break the flour tortilla into pieces the size of the thermos bottom. Heat the sauce very hot. Layer tortillas, cheeses, sauce and spinach, which will melt together nicely. Cap quickly and by lunchtime you'll have a warm, melty lasagna.
