In a small pot, combine the beef broth, soy sauce, lemon juice, honey, ground ginger, minced garlic, liquid stevia, sesame seeds, chopped green onion, and paleo flour. Whisk the ingredients together until the flour dissolves, and heat the liquid over low heat. When the pot reaches a simmer, add the butter to the sauce. Reduce the heat until the sauce is bubbling and the butter melts. Stir the sauce and allow it to reduce until it is thickened.
Set the sauce aside to cool for the remainder of the recipe. Cut chicken breast into 1-bite or 2-bite pieces – about 4 pieces per serving. Add the chicken bites to a mixing bowl and toss them with salt, pepper, onion powder, and olive oil. Meanwhile, heat a non-stick pan over medium-high heat on the stove. Once the pan is hot, pour the seasoned chicken into the pan.
Cook the chicken bites until they’re cooked through and golden brown on all sides. Once the chicken is cooked, add the hot pieces to a larger, clean mixing bowl. Pour the thickened sauce from Step 1 over the chicken, and fold the chicken over in the sauce until it’s all coated. Allow the honey garlic chicken to cool for a few more minutes as the sauce re-thickens before serving.
