Can This Recipe Support Weight Loss Goals?
Yes, these fajitas can fit into a balanced eating plan. They are loaded with vegetables and can be made with a moderate amount of oil. For a lighter meal, use whole-grain or lower-calorie tortillas and increase the vegetable-to-tortilla ratio.
Does This Recipe Fit a High-Protein Lifestyle?
Vegetable fajitas alone provide moderate protein, but they can easily become more protein-rich. Add black beans, pinto beans, tofu, or tempeh to the filling for a stronger plant-based protein base. Serving them with a bean-based side also makes the meal more satisfying.
