When I wrote the recipe I used traditional ground beef, usually 70/30. You can use leaner ground beef, all the way up to 95/5. You can also use ground turkey or ground chicken to make the meat. Ground chicken or turkey is lower in fat and calories. If you want the lowest fat version, use breast, but be careful because the meat tastes dry since it is missing the fat. Also, make sure to drain the fat. This is the easiest way to make taco fries healthier.
