This is my favorite:
3-4 Roma tomatoes - seeded and diced
1 medium white onion - diced
1-2 tsp. dried cilantro
2-2 jalapeno peppers - I actually have started using the diced jalapeno in a jar
1-2 Tbl. lime juice
Combine all the ingredients and store in an air tight container and chill.
I'm the only one in my house that eats it so that is why it's a small amount.
You can adjust the qty.
Finally things have started clicking for me, my knees, my elbows, my back, etc...
