What is your homemade salsa recipe?

So, I started making tofu at home and I bought a blender for grinding soybeans. I’ve also started making homemade salsa with it, which is really easy and yields very fresh salsa.

@La_chica_gomela loves the salsa I make in it, but I think it comes out a little bit bitter. I don’t understand why. Here’s what I am using to make it:
Onions, tomatoes, poblano, garlic, cilantro, lime or lemon juice, salt.

I would love to see some recipes for the best salsa ever. @La_chica_gomela prefers mild salsas, but we can handle a little heat.

Share your recipe! If you don’t, it will die with you.
