What You’ll Need To Do
Time required: 35 mins
Alright, let’s get cooking! This recipe is super easy, fast, and makes you feel like a total meal prep champion.
Step 1: Season the shrimp.
Toss your shrimp in a large bowl with half of that fajita seasoning. Give it a good mix—don’t be shy. Let it hang out and soak up those flavors for about 15 minutes while you get everything else ready.
Step 2: Cook the shrimp.
Heat up 1 tablespoon of olive oil in a large skillet over medium-high heat. Add the garlic and let it do its thing for about 30 seconds until it smells amazing. Now toss in the shrimp and cook for 4-5 minutes, stirring occasionally, until they’re pink and cooked through. Take them out and set them aside—you’ll see them again soon!
Step 3: Sauté the veggies.
In the same skillet (no need to dirty another pan!), add another tablespoon of olive oil. Toss in the onions and bell peppers along with the rest of the fajita seasoning. Stir-fry for 5-7 minutes, or until the veggies are as tender or crisp as you like them.
Step 4: Assemble like a pro.
Grab four meal prep containers and divide the shrimp, veggies, and cauliflower rice evenly between them. Boom—meal prep magic! Eat one right away if you can’t wait, or stash them in the fridge for up to 4 days.
Serving idea: Top it off with some avocado slices, a squeeze of fresh lemon, and a sprinkle of cilantro. Fancy but totally doable.

Helpful Tips for Success
1| Don’t Overcook the Shrimp 🦐 – Shrimp cook fast! Keep an eye on them and pull them off the heat as soon as they turn pink and opaque. Overcooked shrimp = rubbery shrimp.
2| Slice Veggies Evenly 🌶 – For perfectly cooked veggies, make sure to slice your bell peppers and onions to a similar thickness. This way, everything cooks evenly.
3| Pat the Shrimp Dry – If your shrimp are wet, they won’t sear properly. Give them a quick pat with paper towels before tossing them with the seasoning.
4| Customize the Heat Level 🔥 – Want it spicy? Add diced jalapeños or extra chili powder. Keeping it mild? Reduce the spice blend to your taste.
5| Let the Veggies Brown – Don’t rush the veggies. Let them sit for a bit in the skillet to get that nice caramelization—it’s worth it for the extra flavor!
6| Meal Prep Like a Pro 🍱 – Let everything cool before sealing your meal prep containers to avoid excess moisture buildup. Keeps things fresh longer!

Serving Ideas
1| Fajita Bowls 🥗 – Serve over cauliflower rice (or regular rice if you’re not watching carbs) and top with avocado, salsa, and a dollop of dairy-free sour cream.
2| Lettuce Wraps 🌿 – Use large lettuce leaves (like romaine or butter lettuce) to make low-carb fajita wraps. Great for a crunchy, fresh twist!
3| Stuffed Bell Peppers 🌶 – Fill halved, roasted bell peppers with the shrimp and veggies for a fun, baked variation.
4| Fajita Salad 🥬 – Toss the shrimp and veggies over a bed of greens. Drizzle with a zesty lime vinaigrette and sprinkle with fresh cilantro.
5| Taco Night Style 🌮 – Grab some low-carb tortillas, and turn this meal into taco night! Add your favorite toppings like shredded cabbage, pico de gallo, or guacamole.
