Creating Spicy Shrimp Packets is easy when you follow these steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C).
2. Prepare Foil: Tear off four large pieces of aluminum foil, about 12 inches each.
3. Combine Ingredients: In a large bowl, combine the shrimp, bell peppers, onion, garlic, olive oil, smoked paprika, cayenne pepper, salt, and pepper. Toss well to coat.
4. Create Packets: Place equal portions of the shrimp mixture onto the center of each foil piece. Drizzle lime juice over each portion.
5. Seal Packets: Fold the sides of the foil over the shrimp mixture, creating a sealed packet. Make sure it’s tightly sealed to prevent steam from escaping.
6. Bake: Place the packets on a baking sheet and bake in the preheated oven for 10-15 minutes.
7. Check for Doneness: Carefully open one packet to ensure the shrimp are pink and opaque. If not, bake for an additional 2-3 minutes.
8. Serve: Remove from the oven and let cool slightly before serving.
