Notes: Tomatillos, which resemble small green tomatoes covered with a papery husk, are available in many supermarkets and in Latino grocery stores. If fresh ones are not available, use 2 cans (12 oz. each) tomatillos, drained. Find green hulled pumpkin seeds (pepitas) in Latino markets and natural-food stores.
1. Pull off and discard husks and stems from tomatillos; rinse tomatillos well and coarsely chop. Rinse and stem chilies. Remove seeds from poblanos. For a mild salsa, remove seeds from jalapeños. Coarsely chop all chilies.
2. In a food processor or blender, combine tomatillos, poblanos, jalapeños, garlic, green onions, cilantro, pumpkin seeds, vinegar, cumin, and oregano; whirl until smooth. Add hot sauce and salt to taste.
