Preheat the oven to 350°F and grease a 9x13-inch baking dish.
In a skillet, melt butter and sauté the bell pepper and onion until soft. Add garlic and cook for 1 more minute.
Add shrimp and cook for 2-3 minutes until just turning pink. Reduce heat and stir in cream cheese until melted. Add salt, chili powder, cilantro, and lime juice.
Fill each tortilla with 1/3 cup of the shrimp mixture and 1 tablespoon of cheese. Roll tightly and place seam-side down in the dish.
Mix salsa verde and cream in a bowl, then pour over the tortillas. Sprinkle with the remaining cheese.
Bake uncovered for 20-30 minutes until golden brown. Let sit for 10 minutes before serving.
