Preheat the oven to 350 degrees. On a sheet pan, lay out the shrimp, peppers, and onion. Drizzle oil over top and sprinkle both packets of fajita seasonings over top. Use tongs to mix. Cook for 15 minutes, or until the shrimp is just firm and the peppers and onions are cooked and slightly brown.
In a food processor, mix avocados, sour cream, cilantro, salt, garlic and lime until smooth and almost fluffy/airy. Taste and add more salt or an optional dab of hot sauce if needed.
Serve everything buffet style with tortillas, queso fresco, avocado cream, cilantro, hot sauce and salsa. Enjoy!
