You could make seven layer dip with the beans, avocados, cheese and sour cream. Do you have salsa? Just make a layer of beans, then s/c, a little cheese, guacamole(with the avos), salsa, more cheese....My 20 month old like nachos for dinner, that's what we had last night, instead of taco salad.
I ended up breaking down at the store and buying the couple things to make 7 layer dip, because of Cinco de Mayo all Mexican type foods are on a big sale, so a can of refried beans was .59, and a little tub of guac was 1.59 so I went to the store and spent 11.00, plus I bought 2 bags of tortilla chips and sour cream, and a gallon of milk, not too bad. I figured that we could afford those couple things, I think on Monday I will be getting a case of the refried beans because they are on a really great sale, and I am in the process of stockpiling things for winter when they are on good sales, which these are 1/2 price and I use them in tacos all the time.
