• Adjust rack to top position and preheat oven to 425 degrees. Wash and dry produce. • Cut cauliflower into bite-size pieces if necessary. Halve, peel, and finely dice onion. Core, deseed, and finely dice bell pepper. Finely dice celery. Pick parsley leaves from stems; mince leaves.

• Toss cauliflower on a baking sheet with a large drizzle of oil, half the Cajun Spice Blend (you’ll use the rest later), salt, and pepper. Roast on top rack until tender and golden brown, 20-25 minutes.

• Meanwhile, in a small pot, combine rice, half the stock concentrates, 3/4 cup water (11/2 cups for 4 servings), a drizzle of oil, salt, and pepper. Bring to a boil, then cover and reduce heat to low. Cook until rice is tender, 15-18 minutes. Keep covered off heat until ready to serve.

• Heat a large drizzle of oil in a large pot over medium-high heat. Add onion, bell pepper, and celery; cook, stirring occasionally, until browned and softened, 6-8 minutes. Season generously with salt and pepper. • Add another drizzle of oil to pot. Sprinkle in flour and remaining Cajun Spice Blend; cook, stirring, until lightly toasted, 1-2 minutes more. Rinse shrimp under cold water. Pat shrimp or chicken dry with paper towels and season all over with salt and pepper. Heat a drizzle of oil in a large pan over medium-high heat. Add shrimp or chicken; cook, stirring occasionally, until cooked through, 3-4 minutes for shrimp, or 4-6 minutes for chicken. Transfer to a plate.

• Add diced tomatoes, remaining stock concentrates, and 11/4 cups water (21/2 cups for 4 servings) to same pot; stir to combine, scraping up any browned bits from bottom of pot. • Bring to a boil, then reduce heat to low, cover, and cook until slightly thickened, 7-10 minutes. • Stir in roasted cauliflower and half the parsley. Taste and season with salt and pepper. Add shrimp or chicken to stew along with cauliflower.

• Fluff rice with a fork. • Divide rice between bowls on one side; serve stew alongside rice. Garnish with remaining parsley and serve. Chicken is fully cooked when internal temperature reaches 165°.
