2 large green bell peppers
1 large white onion
3 Tbsp of minced garlic
2 scallions (optional)
Cut peppers into large pieces, removing the stem and seeds.
Chop onion into large chunks.
Put all ingredients into a food processor or blender and pulse until finely chopped. The consistency will be close to a paste and should yield around 1 quart or 4 cups.
Store in an airtight container in the refrigerator, fill an ice cube tray, or portion out and freeze for another time.
