These are easy to throw together and good.  A winner every time in my opinion.  I served this with yellow rice.

Mexican Tostadas

Store bought tostadas
Can of refried beans
Shredded cheddar cheese
Shredded lettuce
Diced tomato
Diced avacado
Salsa
Fresh diced cilantro

Warm oven.  In a saucepan, heat beans through over low heat.  Prepare all your toppings.  Warm tostadas in oven.  Remove and spoon a thin layer of beans on top, topping with cheese.  Put them back in the oven for 2 minutes or until cheese is melted.  Remove and sprinkle with shredded lettuce, diced tomato, diced avacado, salsa, and minced cilantro.  Serve immediately.  Eat like a slice of pizza.
