I also made some salsa for the Saturday party and brought extras to work. People asked me for the recipe so here it is. No pictures--sorry. Most of the amounts are rough estimates as I kind do it by eye. Enjoy!
8 plum tomatoes, cored, seeded, and diced (you can use any type of tomatoes, the plum tomatoes looked good and cheap)
1 medium onion, diced
juice of 1 lemon or 2-3 limes (watch the seeds)
2 tbsp chopped cilantro
1 tsp dried ground chili (more or less depending how hot you like it)
1-2 fresh chilies, minced finely (you can use whatever fresh chili you like, jalapenos, serrano, thai, add more or less depending how hot you like it)
Salt to taste
The proportion to tomatoes to onions should be 2/3 tomatoes to 1/3 onions. Mix ingredients together. The longer you let it sit, the hotter it gets.
