Queso

1/2 lb. white American cheese, chopped into chunks
1/4 cup water, more as needed
2 pickled jalapeños, chopped
1/8 cup onions, diced

Put cheese, water, peppers and onion in a glass bowl. Microwave for 1 minute. Stir, then continue in the microwave for 30 second intervals, stirring in between. It will gradually start to thicken. Add more water if it begins to get too thick. 

Serve warm with tortilla chips. Can place in a crockpot on the low setting. Refrigerate leftovers and reheat the same way as above.
