Marinate the shrimp.
In a medium bowl, whisk together the olive oil, chipotle powder, cumin, garlic powder, smoked paprika, salt, black pepper, lime juice, and minced garlic. Add the shrimp and toss until evenly coated. Let the shrimp marinate for 5–10 minutes while preparing the remaining ingredients.
Prepare the rice.
Cook the white or brown rice according to the package directions. Fluff it gently with a fork, then cover and keep warm until you are ready to assemble the bowls.
Sear the shrimp.
Heat a large skillet over medium-high heat. Arrange the shrimp in a single layer and cook for 2–3 minutes per side, or until opaque, cooked through, and lightly charred around the edges. Transfer the shrimp to a plate.
Make the dressing.
Add the olive oil, fresh lime juice, chipotle powder, cumin, and salt to a small jar. Close tightly and shake until the dressing is emulsified. Taste and adjust the lime or salt if desired.
Prepare the toppings.
Halve the cherry tomatoes, dice the cucumber, thinly slice the red onion, slice the avocado, and prepare the spinach or mixed greens.
Assemble the bowls.
Divide the warm rice between serving bowls. Add the greens, tomatoes, cucumber, red onion, and avocado. Arrange the seared shrimp over the top to complete your Chipotle Lime Shrimp Bowl.
Dress and finish.
Drizzle each bowl with chipotle lime dressing. Sprinkle with fresh cilantro and add a squeeze of fresh lime. Top with sliced jalapeños if you prefer extra heat, then season lightly with salt and black pepper.
Serve.
Gently mix the ingredients to distribute the dressing, or enjoy each component separately. Serve immediately while the shrimp and rice are still warm.
