Add ingredients for herb seasoning mix into a small bowl then stir to combine and set aside.
Add bacon to a large skillet over medium heat then brown. Scoop bacon onto a paper towel-lined plate then drain all but 1/2 Tablespoon bacon fat from skillet (eyeball it), reserving extra bacon fat. Turn heat up to medium-high then add chicken to the skillet. Season with homemade seasoned salt and pepper then add 1 teaspoon herb seasoning mix and cook through. Scoop chicken onto a plate then set aside.
Turn heat down to a touch above medium then add 1 Tablespoon reserved bacon fat into the skillet (add extra virgin olive oil if needed to reach 1 Tablespoon fat.) Add sweet potato noodles then season with homemade seasoned salt and 1 teaspoon herb seasoning mix, and then saute for 3 minutes, tossing with tongs frequently to ensure even cooking. Add water then continue to saute until noodles are al dente, 1-2 more minutes.
Add chicken back into skillet then add buffalo sauce and chicken broth. Saute until chicken is heated through and noodles are tender, 1 minute. Remove skillet from heat then top with crisped bacon and green onions. Serve drizzled with ranch dressing, if desired.
