In a medium bowl mix 1 tbsp olive oil shrimp, chili powder, cumin, garlic powder, smoked paprika, salt, and pepper. Set aside.
In a large skillet add 2 tbsp extra virgin olive oil over medium-high heat. Add onion and poblano pepper and cook, stirring occasionally for about 4-5 minutes or until tender. Transfer to a plate and set aside.
Add shrimp to skillet and cook for 1-2 minutes per side over medium high heat until cooked through. Add onion and poblanos back into the skillet and gently mix together cooking for another minute. Add lime juice and mix. Turn off heat and serve in lettuce cups or your favorite tortillas (if not Whole 30 we love Siete almond flour tortillas) and add any toppings!
