This post was developed in collaboration with BUSH’S slow-simmered chili beans and Hunt’s vine ripened tomatoes.

Starting with high-quality canned beans and fire-roasted tomatoes makes a big difference in the depth of flavor for any chili. In this recipe, BUSH’S slow-simmered chili beans add heartiness and texture while Hunt’s fire-roasted diced tomatoes bring a smoky brightness that complements sautéed fajita vegetables. The result is a colorful, gluten-free vegetarian chili that’s ready in less than half an hour.

This one-pot recipe is part of my 29-minute meal approach: quick to prepare, full of flavor, and easy to clean up. I call it “Whitney’s Pepper Fiesta Vegetarian Chili” because the mix of red, green and yellow bell peppers makes it feel like a little celebration in the bowl.

Tips, Variations and Storage

Tips for the best results: use a mix of red, yellow and green bell peppers for color and balanced sweetness. Portabella mushrooms add a meaty texture, but you can substitute cremini or button mushrooms if preferred. If you like more heat, add diced jalapeño with the bell peppers or a pinch of cayenne pepper with the spices. For a thicker chili, simmer a few minutes longer with the lid off.

Variations: add a drained can of black beans or pinto beans for more protein and variety, or stir in cooked quinoa for added texture and nutrition. For a smoky twist, finish with a dash of chipotle in adobo.

Storage and reheating: cool leftover chili and store in an airtight container in the refrigerator for up to 3–4 days. Reheat gently on the stove over low-medium heat with a splash of water or stock, or microwave individual portions until warmed through. This chili also freezes well in a sealed container for up to 3 months—thaw overnight in the refrigerator before reheating.
