I've decided to throw my guy friend a 40-something b-day party. I think a Mexican theme would be fun and delicious, and I'd like to do a nachos bar with chips, salsa, beans etc. I have a one of those crock pots with three pots in a single base and I was thinking that it would be perfect to keep the cheese sauce and beans warm. Problem is, I need a recipe for nacho cheese sauce. can anyone help? And if you have any other ideas for easy (vegetarian) Mexican snacks, please pass them along!
