Preheat oven to 350 degrees
Cut tomatillos in half and place cut side down on foil-lined cookie sheet, with oil
Slice 1 jalapeno lengthwise; remove seeds (unless you want it hot), and add it to the pan
Add 2 garlic cloves to the pan
Chop onion into medium sized chunks and add to roasting pan
Rub oil on foil and coat everything slightly
Roast in oven for 15 minutes, turning once midway through
Add all ingredients, including cilantro and salt/pepper to a food processor and pulse. You don't want it too smooth! Keep some thickness to it.
Cool and serve with chips, with eggs for breakfast tacos, or use as you would with any other salsa! Enjoy!
