This wonderfully simple shrimp taco is a delicious use of an “al pastor” style, spiced marinade. Although traditionally used on pork or lamb, this marinade works wonders with shrimp. The pineapple not only flavors... the shrimp, but in combination with the orange juice, it actually starts to soften and “cook” the shrimp as it marinates. Only a few minutes in the pan, and you can fold the shrimp into a warm taco for an easy, delicious meal.
In a large bowl, combine annatto powder, chili powder, orange zest, orange juice, 2 tablespoons olive oil, and pineapple. Season with salt and pepper. Add shrimp and stir until shrimp is coated. Leave to marinate 10 to 15 minutes.
Place a saute pan over medium heat and add remaining oil. Add marinated shrimp and cook for about 10 minutes, until shrimp turn pink. Remove from heat.
In a dry saute pan over medium-low heat, place one tortilla at a time in pan to heat through.
Place a portion of shrimp onto each tortilla. Garnish with cilantro and red onion.

If you have a cast iron grill pan at home, cook the shrimp in that.
