This delicious, yet very easy dip has been a hit at every party I've prepared it for. It's so good, we'll make a batch and have it for dinner every so often. People have told me it's addictive. I rarely have to bring any home after a party. I've been making this dip for many years, so I'm not sure where it came from. When making it for my family, I use refried beans with jalapenos, hot McCormick Taco Seasoning mix, and velveta cheese with peppers. This combines for quite a kick. For guests or a party, I use reqular refried beans and velveta, but the hot taco seasoning is a must. For Christmas parties, I use the red and green tortilla chips.
