Tips from an expert home chef

• The cilantro lime marinade will be kind of thick. That’s ok! You want it to coat and stick to the shrimp and fajita veggies as much as possible.
• Use whatever tortilla shells you want. Use lettuce wraps or keto tortillas for low-carb or you can use corn or larger fajita tortillas if desired.
• Make it a fajita bowl. You could even skip the shells entirely and serve it in a bowl with cauliflower or regular rice and/or some other greens or veggies.
• Clean, peel and remove the tail from the shrimp before cooking. This will save you the hassle of taking the tails off the hot cooked shrimp :).
• Don’t forget the toppings! We love a good dollop of our homemade chipotle aioli sauce. Or some chopped fresh cilantro and avocado are great options too.
