One of my favorites for meal prepping are refried beans.
You can easy portion them, keep them in the fridge and you can quickly reheat them. As well it is not much more effort to do a large portion when you do the normal cooking. Last time I did a Mexican dinner and included refried beans. Instead of one can of beans I used 3 cans. This gives me additional 3 portions for meal prepping.
1 can kidney beans
½ onion, finely chopped
1 garlic clove, peeled & finely chopped
1/2 teaspoon cumin
1 teaspoon tomato puree
2 cups of water
oil
Enjoy your beans.
