Preheat your oven to 425°F.
Place wooden skewers in a bowl of water to soak for 20 minutes. This prevents them from burning in the oven.
In a large bowl, combine the shrimp, olive oil, chipotle powder (or chipotle pepper in adobo paste), fresh garlic, chili powder, coriander, oregano, onion powder, cumin, salt, lime juice, and cilantro. Mix everything together well.
Thread the shrimp and bell peppers onto the skewers in an alternating pattern. Make sure to brush the peppers with any extra marinade.
Place the skewers on a rack and bake in the oven for about 6 to 7 minutes, or until the shrimp turns pink. For extra browning, you can turn on the broil setting for 1 to 2 minutes.
Serve the shrimp skewers immediately and enjoy your delicious meal!
