Take a saute pan and melt butter in it by heating at a low flame.
To initialize your process, add the diced veggies including onion, tomatoes, and jalapeno.
Cook until the veggies get soft. Keep the temperature lower because as long and slow the process is, the better taste will develop in it.
Then, in the next step slice the Velveeta into smaller cubes. Throw these cubes in a crockpot and then add all the cooked veggies.
Cook for some time so that the cubes of Velveeta will melt and get merged with the veggies. In the end, add the sour cream and cook for a few minutes.
Your amazing Queso dip is ready. Serve it with tortilla chips to your family and kids and they will be a fan of it.
