Key Ingredients and Their Benefits
1. Sweet Potatoes
Sweet potatoes are a nutrient-dense root vegetable rich in beta-carotene, which the body converts to vitamin A, supporting vision, immunity, and skin health. They provide complex carbohydrates for steady energy and are high in fiber, promoting digestive health and satiety.
2. Black Beans
Black beans are an excellent source of plant-based protein and fiber, which support muscle maintenance, gut health, and stable blood sugar levels. They are also rich in iron, magnesium, and folate, essential for energy production and cellular health.
3. Taco Shells
Corn tortillas or whole-grain tortillas provide additional fiber and micronutrients while serving as a gluten-free option when using corn. They offer a neutral base that complements the bold flavors of the filling.
4. Flavor Enhancers
- Spices: Cumin, smoked paprika, chili powder, and garlic add depth and complexity
- Citrus: Lime juice brightens the flavors and adds vitamin C
- Fresh Herbs: Cilantro or parsley enhances aroma and adds phytonutrients
- Avocado or Plant-Based Yogurt: Adds creaminess and healthy fats for nutrient absorption
