Louisiana BBQ Shrimp

Preheat Traeger grill to 400F. In a cast iron skillet, melt butter. Sauté onions, poblanos, peppers, shallots, garlic, lemon, and Cajun rub in the butter until the veggies are softened. Add in Worcestershire sauce, Dijon mustard, lemon juice, hot sauce, and thyme leaves. Taste test and adjust seasoning with salt and pepper. Simmer on low. Grill shrimp until they are just turning opaque (approximately 14 minutes, depending on size and starting temperature). Then toss the grilled shrimp with the prepared sauce. Layer the shrimp on hot fluffy white rice and pour over the remaining sauce. Serve with a crusty French baguette to sop up the sauce if desired.
