From what I understand, "salsa" means "sauce" which could be ANYTHING from pico to fermented hot sauce to gravy to fruit salad dressing ......
But, guessing you're looking for a typical pico de gallo style salsa, here's the recipe I've used for several years when doing the salsa project at school- (and also a black bean salsa)
edit- I copy/pasted the recipe and the text is a little funky, but the first recipe has 2 measurements, for a small batch and large batch. The measurements are on the correct lines, you just have to separate the measurements in the text.

NOTES-
Briefly rinse tomatoes under hot water to remove any wax or oils that may have been put on the tomatoes to prevent mold growth during shipping.
Tomato Paste is available in re-closable tubes. Just squeeze out what you need, keep the rest in the fridge for later. Look for it in the tomato sauce/paste section of the grocery store.
Smash whole cloves of garlic with a clean can or the flat side of a knife for easy peeling.
