My Salsa Fresco

This Salsa is a huge hit here. I actually got the idea from Taco Bell.  They have a fresh Salsa that is ok......but I knew I coould make it better.
This is my results:

3 large under ripe tomatoes. They need to be a little green or very firm. 
1-2 large WHITE Onions( has to be a sweet white onion.   Maui's Sweet White Kula onions are the best for this, but hard to find in Alaska)
3-4 T chopped fresh cilantro

juice of two fresh limes
garlic powder
paprika
salt
white pepper

OPTIONS: to make this HOT add:  About a 1/4 of a cup of finely chopped pickled jalapenos, or 3 fresh chopped jalapenos.

You want to make this early in the day, about 3-4 hours before you are serving.  

Chop the tomatoes up in small cubes.   Careful to keep all the juices you can. Put into a GLASS mixing bowl. NOT metal.  Metal seems to change the taste of this recipe.  Chop the onion up into small cubes roughly the same size as the onion. Add to the tomatoes.   Add finely chopped cilantro and the juice of the limes.   Season with the Garlic powder and paprika( about a half tsp of each) 1/4 tsp of white pepper, and 3/4 tsp of salt. You can add hotter spices at this point if you want it hot. Toss well.  Let this sit in the fridge for 3 or 4 hours before serving.
