Salsa

Tomatoes
Green bell peppers
Onions

Jalapeños

Cilantro
Garlic
Salt
Lime juice

Quarter or eighth your tomatoes, and cut off the white core.  Fill the food processor bowl once.  Pulse to a finely diced consistency.  Pour into another bowl.  Fill it up again almost to the top with tomatoes.  In the top of the second bowl (or first, it really doesn't matter), add salt to taste, a couple of cloves of minced garlic, and about 1/3 cup fresh cilantro.  Pulse again until the tomatoes and cilantro are well diced.  Pour out the bowl.  Fill half of your food processor bowl with bell pepper, then add your jalapeños.  I usually scrape the membranes and seed them first, but you can leave the seeds in for more heat.  Fill the rest of the bowl with onions, and pulse again to a similar consistency.  Check for larger chunks, but add the peppers and onions to the tomato bowl.  Mix it up, and add about a tablespoon of lime juice (fresh if you have it, but I've used it from a bottle).  Taste it, and add more salt or lime as needed.
