This is a great solution to dinner-on-the-run. It's delicious, nutritious and (sometimes, most importantly) FAST.
can of black beans
your favorite salsa
cheddar cheese, shredded
corn or flour tortillas
Heat the beans in a pot or skillet on the stove. I usually let 'em boil gently in the cooking water that came in the can for about 5 minutes.
Meanwhile, steam the spinach. The easy way to do this is rinse the leaves well, put them in a microwaveable bowl, cover and cook for 1 minute. When cool enough to handle, chop the steamed spinach.
Assembly is up to you. If you have big tortillas, pile in your ingredients, roll it up (you may have to heat the tortillas first to avoid breakage), and enjoy! If you have little tortillas, you might want to layer the ingredients on one tortilla, top it with the other tortilla, and bake or pan fry until the cheese is melted.
It's very easy to adapt these to include whatever you like. We often add in corn and brown rice if we have some on hand. Sometimes we toss in bite-sized cooked chicken too. It's up to you!
