Ingredients

• 1 cup millet
• 2 cups water
• 1 can (15 oz) canned chickpeas, drained and rinsed
• 1 medium zucchini, diced into 1/2-inch cubes
• 1 red bell pepper, diced into 1/2-inch cubes
• 1 medium yellow onion, chopped
• 3 garlic cloves, minced
• 1 can (14.5 oz) canned diced tomatoes
• 3 tbsp olive oil
• 1 tsp ground cumin
• 1 tsp smoked paprika
• 1/2 tsp dried oregano
• 1 tsp salt
• 1/2 tsp black pepper
• 1/4 cup grated Parmesan cheese (optional)

Instructions

1. Step 1: Preheat oven to 400°F. Rinse 1 cup millet under cold water, then combine with 2 cups water in a medium saucepan. Bring to a boil, reduce to simmer, cover, and cook for 15 minutes until water is absorbed and millet is fluffy.
2. Step 2: While millet cooks, toss 1 diced zucchini, 1 diced red bell pepper, and 1 chopped yellow onion with 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper on a baking sheet. Roast in oven for 20 minutes until tender and edges slightly caramelize.
3. Step 3: Heat 1 tbsp olive oil in a large skillet over medium heat. Add 3 minced garlic cloves and sauté for 30 seconds until fragrant. Add 1 tsp ground cumin, 1 tsp smoked paprika, and 1/2 tsp dried oregano; cook for 1 minute to bloom spices.
4. Step 4: Stir in 1 can (14.5 oz) diced tomatoes with juices and 1 can (15 oz) drained chickpeas. Simmer on low for 5 minutes until sauce thickens slightly.
5. Step 5: In a large mixing bowl, combine cooked millet, roasted vegetables, and tomato-chickpea sauce. Adjust salt and pepper to taste.
6. Step 6: Transfer mixture to a greased 8x8-inch baking dish. Sprinkle 1/4 cup grated Parmesan cheese evenly on top if using. Bake uncovered at 400°F for 15 minutes until cheese browns and casserole is heated through.
