What all peppers go into your salsa verde? Here is what I usually toss into mine:

7 medium tomatillos (dehusked, ping pong ball sized or thereabouts)
5 chile de arbol (cut the stems off)
1 small habanero (pull the stem off)
1 small jalapeno (split and deseeded)
1 medium anaheim chile (split and deseeded)
1 medium hatch chile (split and deseeded)

When hatch aren't in season and available, I'll sub another of the green chiles that my local Cardenas or La Bonita usually has.
