I have been lucky enough to get my own meat grinder. With it I decided to grind our own beef for tacos. Ground Sirloin Tacos are delicious, they're fresh and you know exactly what's in them. You can grind in your favorite flavourings, like garlic, onions and even the taco seasoning itself, to achieve maximum awesome. These tacos were amazing. I added the homemade taco seasoning, garlic, onions, and peppers, and ground it right into the meat itself before grilling. Just remember to grind from frozen, the meat fat gets caught in the grind wheel and makes an awful mess.
