Salsa Macha

Combine oil, peanuts, garlic, and sesame seeds in a large saucepan. Cook over medium-high, stirring often, until garlic and sesame seeds are golden, 5 to 6 minutes. Remove from heat, and stir in chiles. Let cool 5 minutes. Stir in vinegar, salt, and oregano. Let stand until cool, about 20 minutes.

Pour mixture into a blender or food processor, and pulse until garlic and peanuts are finely chopped (do not overprocess or puree). Store in an airtight container in refrigerator up to 2 weeks.
