I happen to have a recipe handy, not tried it but it sounds about right (I make Salsa Fresca ... according to wikipedia aka pico de gallo
), let me know what you think if yo udecide to try it
1 1/4 lb tomatoes, seeded
1 medium onion diced
1 - 2 fresh jalaps or serranos, seeded and finely diced
2 cloves garlic minced
1 medium diced green bell pepper
2 T fresh lemon juice
1 T fresh oregano (or 1 t dry)
1 bay leaf
1/2 t sugar
<condensed instructions>
Blend tomatoes to desired consistency.
Put it all together in a pot, bring to boil, reduce heat, simmer uncovered 30 minutes (or until it gets to desired consistency).
In your case you might want to puree it all before cooking or perhaps puree some of it with a stick blender after the fact.
Edit: don't forget to pop the bay leaf out before blending
It calls for 1/4t salt when simmering but I'd honestly test it with my chips or whatever THEN salt it.
I'd roast all the peppers like Kevin suggested, not tried roasting tomatoes but I'd give that a go too.
The fresh herbs would really make this stuff. I'd throw them in half way through simmering. Could probably stand some fresh basil like maybe 1t, perhaps a pinch (1/8t) of cumin and/or toasted ground coriander (1/4t).
I'd probably leave the bay leaf in a day or two.
That's how I'd do it. Might use more like 1 T of sugar, not sure.
