My favorite dip is simple and easy to make with things that you can keep in your pantry.
Black Bean & Corn Dip
2 cans black beans, drained and rinsed
1 can petite diced tomatoes
1 can corn, drained
Just mix it all up and add whatever seasonings you like. I keep it simple and just throw in some diced green onions. The last time I made it, I had some leftover salsa in the fridge, so I added that too. This is a very fresh-tasting dip, and it works well with the scoop-type chips.
