In a large skillet over medium-low heat, melt 2 tablespoons butter until bubbly. Add the chicken and turn the heat up to medium-high.
Cook the chicken, tossing frequently, for 7 minutes, until chicken is golden brown on the outside.
Remove the chicken bites from the skillet and add the remaining butter and garlic to the skillet. Saute for 1 minute.
Add the chicken broth to the skillet, and bring to a boil, scraping up the browned bits from the bottom of the skillet.
Stir in hot sauce, turn heat down to low and simmer for 2 minutes. Return the chicken pieces to the skillet and add the lemon juice. Toss to coat. Sprinkle with fresh parsley.
