Steak tacos that you buy from a restaurant may have a lot of hidden calories, but when you make steak tacos at home it's easy to be in control of the recipe and create a healthy meal. A non-fried corn or flour tortilla are among the healthier options. You could even substitute the tortilla for a lettuce leaf or similar. Then, the lean steak and vegetables that make up this recipe are all nutritious and healthy ingredients. Like in these lettuce cups.
