Now, let’s get cooking! Here’s how you can whip up these tacos in no time:

1. Start by marinating the steak. In a bowl, combine half the olive oil, lime juice, chili powder, garlic powder, onion powder, cumin, salt, and pepper. Coat the steak slices in this mixture and let it sit for at least 15 minutes.
2. While the steak marinates, heat a pan over medium-high heat and add the remaining olive oil. Add the shrimp, sprinkle a pinch of salt and pepper, and cook for about 3-4 minutes, until they’re pink and opaque. Remove from the pan and set aside.
3. In the same pan, add the marinated steak slices and cook for about 4-5 minutes, or until your desired level of doneness. I like mine with a bit of a char, which reminds me of those summer BBQs with my family.
4. Warm your tortillas in a dry skillet or directly over the flame of a gas stove for a slight char.
5. Assemble the tacos by layering steak and shrimp on each tortilla, then topping with cabbage, avocado, cilantro, and a dollop of sour cream. Squeeze a bit more lime if you like that extra tang!
