Pat the shrimp dry with a paper towel first, since this helps them sear instead of steam. Toss them in a bowl with olive oil, smoked paprika, salt, and pepper. Let them sit for a few minutes so the seasoning really soaks in.
Melt the butter in a large skillet over medium heat until it starts to bubble gently. Add the minced garlic and stir it constantly for about 30 seconds. Watch it closely, because garlic burns fast and turns bitter.
Add the seasoned shrimp to the skillet in a single layer, without overcrowding the pan. Cook for about 2 minutes per side until they turn pink and slightly curled. Squeeze fresh lemon juice over them right before removing from heat.
In a large mixing bowl, add the chopped romaine and pour the Caesar dressing over it. Toss everything gently using tongs so every leaf gets coated evenly. Add the grated Parmesan cheese and toss again lightly.
Start with a base of rice, quinoa, or extra greens if you're using one. Layer the Caesar salad on one side and the garlic butter shrimp on the other. Finish with sliced avocado and a few croutons scattered on top.
Drizzle any extra garlic butter from the skillet over the finished bowl for added richness. Sprinkle a little more Parmesan and cracked black pepper on top. Serve the bowl immediately while the shrimp is still warm.
