Good idea, except her freezer is too full, she said.
I wonder if adding canned refried beans would satisfy. Many years ago, on another forum I used to frequent, a poster shared an easy 5-can soup recipe that includes refried beans. It’s been a very long time since I made it, but I recall it thickened the soup and made it kind of creamy. My recollection is she said it was originally a Weight Watchers recipe.
Found it. The top is her words, not mine (as I DO eat meat.

) The way she wrote it, it looks like the cheese goes into the soup, but I believe it’s just for topping after. At least, that’s what I thought.
