One of my favorite easy recipes with navies is refried beans. Soak them overnight, then drain them, rinse them, and add some water to the bottom, cook them in your crockpot all day with a good pinch of salt, pepper and a T of crisco or fat. After they are well done, mash them, add in cayenne pepper to your liking.
This is great because you can use them to make beef and bean burritos, nachos with beans, cheese, salsa, sour cream, etc
One of my favorite dishes is to chop fresh greens, add a scoop of hot refried beans, a few bite size chunks of leftover grilled chix, a little bit of cheese on top, some chopped avocado or salsa. This makes an excellent lunch or dinner.
