• 3 tbsp fresh lime juice
• 2 tbsp olive oil
• 3 cloves garlic cloves, minced
• 1 tsp ground cumin
• 1 tsp salt
• 1/2 tsp black pepper
• 8 small corn tortillas
• 1 medium red onion, thinly sliced
• 1/2 cup white vinegar
• 2 tbsp granulated sugar
• 1/2 cup water

Instructions

1. Step 1: In a blender, combine 2 chipotle peppers in adobo sauce, 3 tbsp fresh lime juice, 2 tbsp olive oil, 3 minced garlic cloves, 1 tsp ground cumin, 1 tsp salt, and 1/2 tsp black pepper; blend until smooth to create the marinade.
