Ingredients

1 cup quinoa (uncooked)
1 cup frozen corn

2/3 cup reduced-sodium chickpeas (drained and rinsed)
1/2 cup black beans (drained and rinsed)

1 cup red pepper (chopped)
1 cup Roma tomatoes (chopped)

1/2 cup onion (roughly chopped)
1/2 tablespoon cumin
1 tablespoon garlic (minced)

1/4 teaspoon salt
1 1/2 tablespoons sauce from a can of chipotle peppers in adobo sauce
2 cups reduced-sodium vegetable broth

Shredded cheddar cheese (for garnish, optional)
Fresh cilantro (for garnish)

Instructions

Step 1: Spray your slow cooker with cooking spray to prevent sticking.

Step 2: Add the uncooked quinoa, frozen corn, chickpeas, black beans, chopped red pepper, chopped tomatoes, onion, cumin, minced garlic, salt, and chipotle adobo sauce to the slow cooker. Stir until well combined.
Step 3: Pour in the vegetable broth and stir everything again to mix.
Step 4: Cover the slow cooker and cook on high for 3 to 4 hours. Check around 3 hours for doneness; quinoa should be tender and liquid absorbed.

Step 5: Once cooked, season to taste with extra salt and pepper if needed.
Step 6: Garnish with shredded cheddar cheese and fresh cilantro before serving.

Tips & Variations

For extra protein, add cooked shredded chicken or ground turkey before cooking.

Use different beans like pinto or kidney beans to switch up the flavors.
If you prefer less heat, reduce the amount of chipotle sauce or omit it entirely.
Serve with avocado slices or a dollop of Greek yogurt for creaminess.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or on the stovetop with a splash of water or broth to loosen the casserole if it has thickened.
