Sprinkle water on the naan bread. Pre-bake the naan bread for about 3 - 5 minutes or per package instructions. When finished, remove from oven and set aside.
In a medium bowl add the shrimp. Sprinkle with salt and pepper. Toss with olive oil and cajun seasoning.
In a large skillet over medium heat, melt butter. Add the shrimp and cook for about 2 minutes, and turn to cook the other side. Add minced garlic and stir continuously for about a minute. Stir to cover shrimp with butter and garlic.
Pour shrimp over naan bread. Divide evenly between the two flatbreads.
Sprinkle Queso Fresco (or feta) cheese and green onions on top of each flatbread.
Bake for 7 to 8 minutes (time may vary depending on oven.)
Remove from oven.
Add 1/4 cup mango habanero salsa to each flatbread.
