Heat the oven to 425°F. Slice the peppers and onion, toss with 1 tbsp oil and half the fajita seasoning, and roast on a sheet pan 8 minutes.
Toss the shrimp with the remaining oil and seasoning, add to the pan, and roast 6 to 8 minutes more until pink.
Squeeze lime juice over everything. Warm the tortillas.
Serve family-style with sour cream, sliced avocado, and lime wedges so everyone builds their own.
