Prep the shrimp: Pat shrimp dry with paper towels. Dry shrimp sear better and don’t steam.
Season the shrimp: In a bowl, toss shrimp with 1 tablespoon olive oil, Cajun seasoning, smoked paprika, garlic powder, onion powder, cayenne (if using), salt, and pepper.
Set aside while you prep the veggies.
Prep the vegetables: Cut broccoli into small florets so they cook quickly. Slice the red bell pepper. Toss both with 1 teaspoon olive oil and a pinch of salt and pepper.
Cook the broccoli: Heat a large nonstick skillet over medium-high.
Add broccoli and cook 4–6 minutes, stirring occasionally, until crisp-tender with a bit of char. Add bell pepper in the last 2 minutes. Transfer to a plate.
Sear the shrimp: In the same pan, keep heat at medium-high.
Add the shrimp in a single layer. Cook 2–3 minutes per side until opaque and lightly browned. Don’t overcrowd; work in batches if needed.
Brighten it up: Squeeze lemon over the shrimp.
Taste and adjust salt or spice.
Assemble meal prep: Divide broccoli and peppers into 4 containers. Top with shrimp. Add cauliflower rice or a small scoop of brown rice to each, if using.
Garnish: Add lemon wedges and a sprinkle of parsley.
Let everything cool slightly before sealing the containers.
