There are very few items I will heat and eat straight out of the can. Old El Paso Traditional Refried Beans is one of them. When a guest approvingly guessed I had added lard, my answer was no ma’am, that’s the way they come.
The one embellishment I generally do add is to grate some cheese on top while it’s heating in the saucepan, then cover and let the cheese get nice and gooey, Tex Mex style. After the meal, I’ll mix in leftover chopped onion, jalapeños, salsa and whatever other bits might remain from the condiment tray and use the result to make quesadillas. Give this a try.
