The spiciness of this light yet satisfying chili is complemented by the subtle sweetness of corn and winter squash. Queso fresco is a crumbly, slightly salty Mexican cheese that's available in many large supermarkets. If you can't find it, substitute crumbled feta or farmer cheese. For a heartier chili, add one cup thawed frozen meatless crumbles. For a vegan version, use shredded soy cheddar or mozzarella cheese.
Heat olive oil in a large nonstick skillet over medium heat. Add onion, bell pepper, and garlic; cover and cook 5 minutes or until tender. Add chili powder and cumin; cook 1 minute, stirring constantly.
Place onion mixture in a 5-quart electric slow cooker. Add butternut squash and next 6 ingredients (through chiles). Cover and cook on low 8 hours or until vegetables are tender and chili is thick. Sprinkle with cheese; serve with lime wedges.
