Step-by-step
To make the marinade, juice the lime and place in a small bowl together with the spices (chile powder, cumin, salt and pepper) and olive oil. Whisk to combine — the mixture will thicken.
Peel and slice the onion and slice the bell peppers. Mince the garlic. You can use one green bell pepper plus three other bell peppers (red, yellow and/or orange).
Place the peppers in a bowl and add the red onion and garlic. Pour over half of the marinade. Toss to combine.

In another bowl combine the shrimp with the remaining marinade. Place in the fridge for at least 30 minutes or overnight.

Remove the peppers from the fridge. Place in a tray together with the marinade and bake at 200 °C/ 400 °F (fan assisted), or 220 °C/ 425 °F (conventional) for 10 minutes, tossing and rotating the tray halfway to ensure even cooking.

After 10 minutes, turn on the broiler, add the marinated shrimp and cook on high for another 5 to 8 minutes. (You will have some marinade left from the prawns. Do not pour it into the tray as it would make the meal too watery.)
Remove from the oven and set aside to cool for 5 minutes before serving. Optionally, serve with lime wedges, cilantro (or parsley), sour cream and/or Keto Tortillas. Store in the fridge for up to 3 days.

What temperature do you set the oven?
Well spotted! See step 5. Once I add the shrimp I just broil it on high (240-250 C).
… but what about the temperature for the peppers and onions?
I fixed that part (see step 5) - it was previously missing.
