Empty contents of diced tomato can into your food processor. Place red onion in processor (use the amount to your family's taste- mine likes a small amount of onion). Pick cilantro leaves off the stalks and place in food processor (a few stalks are okay, but it should be mostly leaves). Place slices of pickled jalapeno peppers in processor (this is also to taste, but with only 7-10 slices, my two year-old will eat it.) Pour the can of tomato sauce over the top.

Process until desired consistency is reached. Serve with salted tortilla chips.
