Fresh and simple!
I like to make this when making Fajitas or Tacos, but it is also nice with a big bowl of Tortilla Chips.
1 1/2 - 2 cups tomatoes, seeded and chopped
1/2 cup onion, chopped
2 jalapeno peppers, chopped fine*
handful fresh cilantro chopped
1-2 tablespoons fresh lime juice
dash or two of salt
1 tablespoon olive oil
Toss chopped tomatoes, jalapenos, onion, and cilantro together. Sprinkle with a bit of salt and lime juice, then stir in olive oil.
If the tomatoes are a little too acidic, a little sprinkle of sugar (not too much) will tame that down.
* the heat of the peppers are mostly in the seeds and the white pith they are attached to - depending on how hot or mild you like it add those accordingly.
