In a skillet over medium heat, melt butter. Toss in shrimp and season with onion & garlic powder. Add chipotle peppers in adobo sauce.
Saute shrimp for 2-3 minutes or until no longer opaque, but not fully cooked through.
Add cream and reduce heat to barely a simmer. Cook until shrimp is cooked through.
Working in small batches, mix in cheese. Stir until smooth.
Add lime juice and season to taste with sea salt and pepper. Enjoy over top of zucchini noodles or spaghetti squash.
chipotle peppers in adobo are sold in the international section of most grocery stores in small cans. I puree sauce and peppers, then freeze in small ice cube trays to use later since I never need an entire can. They are very spicy and I caution you to use them sparingly to start.
