Burritos fit both of these criteria. The other night when I didn't feel like cooking, I came up with this to use some leftover rice, some salsa that no one was eating and I was worried it would go bad soon, and a partial can of refried beans. It is good enough that I might consider making up fresh rice, opening a jar of salsa specifically for it, and opening a can of refried beans as well!
large flour tortillas
Cheddar, Monteray jack, colby or a "Mexican" cheese blend
sour cream (optional)
other fillings such as guacamole, seasoned meat, lettuce, etc (optional)
2 tbsp olive oil
Combine the rice with the salsa in desired proportions and heat through. Spread a thin layer of refried beans on each tortilla. Layer seasoned rice, cheese, and any other toppings onto the burrito and fold. Heat oil in a medium skillet over medium heat. Place burrito on skillet and gently brown each side before serving.
