Low Carb Beef And Broccoli Stir Fry (Keto)

"This is a low carb and keto friendly version of my popular beef and broccoli stir fry that's healthy yet doesn't sacrifice on flavor. This recipe yields 11.5 g net carbs per serving. Also great for gluten free diets. Ingredients 3/4 pound flank steak sliced into 1/4 inch thick strips 4 cups small broccoli florets (about 7 ounces) 1/2 cup beef stock 1 tablespoon corn starch 1 tablespoon canola oil For the sauce: 1/3 cup low-sodium soy sauce 3-5 tablespoons sweetener (see post for options)"
