That picture is pretty appetizing right?
I roasted poblanos, tomatillos, half a yellow onion, and one bulb of garlic on the grill.
Let them cool after you char them. Then peel the skin off the poblanos. Pop the cloves out of the softened garlic.
Add everything to the food processor and let it rip. Be sure to add salt and pepper. Lime juice helps too.
Presto. Salsa verde!
