- One of my go to lunch meals when I am trying to lose weight! 361 total calories for all 3! I prep 90/10 ground sirloin by forming 2 pound balls and putting them on the smoker to get a nice flavor and a little outside crisp! Chop them up and freeze in individual 4 ounce servings, which fills 3 of these Keto street taco shells perfectly! Mix up the protein between this, shrimp, pulled chicken, and steak to keep it interesting 🔥🔥
