Follow these steps to create your Spicy Cajun Shrimp Bowl:

1. Prepare the Shrimp: Begin by rinsing the shrimp under cold water and patting them dry with paper towels. Place the shrimp in a bowl and sprinkle with Cajun seasoning, ensuring that they are evenly coated. Set aside to marinate for about 15 minutes.
2. Cook the Vegetables: Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the minced garlic and chopped onion, sautéing until fragrant and translucent, approximately 3-4 minutes. Add the sliced bell peppers and continue to cook until they are tender but still crisp, about 5 minutes. Remove the vegetables from the skillet and set aside.
3. Cook the Shrimp: In the same skillet, add the remaining tablespoon of olive oil. Once hot, add the seasoned shrimp. Cook for about 2-3 minutes on each side, or until the shrimp are pink and opaque. Remove the shrimp from the skillet and set aside.
4. Make the Sauce: Pour the chicken broth and lemon juice into the skillet, scraping up any browned bits from the bottom. Bring the mixture to a simmer, allowing it to reduce slightly for 2-3 minutes.
5. Combine Ingredients: Return the cooked vegetables and shrimp to the skillet, stirring to coat them in the sauce. Season with salt and pepper to taste.
6. Serve: Divide the steamed rice among serving bowls and top with the Cajun shrimp and vegetable mixture. Garnish with freshly chopped parsley.
