My family’s ALL-TIME favorite Dip.
Saute chopped onion, jalapenos(fresh or from a jar) and garlic until soft.
Add shredded cheese. The best is a combo of Sharp Cheddar and Montery Jack, but use whatever you have, if you must.
Pour in some pickeled jalapeno juice and stir over low heat until smooth and melted.
Serve with tortilla chips or crackers.
