It's a lofty claim, but these shrimp tacos are the best I've ever had.
In a large frying pan, heat olive oil on medium-high
Add onions and cook for 5 minutes, until soft
Add garlic and cook for 2-3 more minutes, stirring to ensure it doesn't burn
Add tomato paste and spices to the pan, mixing to coat the onion and garlic mixture
Add shrimp to the pan, stirring to ensure that shrimp is coated with the sauce
Cook shrimp until just opaque on both sides
Serve in tacos with garnishes
