That sounds good. Its pretty close to the ingredients in my pico recipe, except I didn't think of the garlic and I add some celery and lime juice.
I would take a portion of the tomato and blend it into a liquid and add it back to diced veggies.
I never measure or write down anything I do so that means I also never do anything quite the same twice, but I'm thinking I will do this for my wife who has been making noises that I haven't done a salsa in a while.
Dice some veggies, in no particular proportion other than tomato is around 3 to one to the others:
Tomatoes
red and yellow onion
celery
jalapeno ( I scrape the seeds and pith out which allows me to add more- I like the flavor)
bell pepper yellow or orange
chop some cilantro (we like a mega dose)
blend:
some of the tomato
some crushed garlic
some of the cilantro
the juice of a lime
a dash of salt if you use it
add the rest of the diced veggies and the blended liquid to a bowl and let it sit in the fridge for a few hours to let the flavors marry.
I guess to avoid adding water to get enough liquid to soak the diced veggies, you would want to make sure you blended plenty of tomato.
