Last week I made a batch of salsa verde and have enjoyed it on, among other things, steak, eggs, and sweet potatoes. It may not be strictly paleo given that it is made with a number of New World nightshades. Perhaps it falls into a grey area.
I lightly oiled a baking sheet and put on 10-15 tomatillos (husk removed and halved), a large white onion (cut into quarters), one pasilla pepper and two anaheim chilis (all halved, de-seeded, and de-veined), and 5-6 cloves of garlic; and put it under a broiler until things began to blacken. Removed from the oven and peeled the peppers, but didn't sweat getting them 100% clean.
I put the above into a food processor and pulsed until broken down. I then added a bunch of cilantro and a bunch of flat parsley (large stems removed) and pulsed, but not all at once so as to get everything well chopped. Last, I added a bit of sea salt and white pepper to taste.
Be advised that it packs some heat. Oh, and it's good hot or cold. ENJOY!!
