Cut chicken tenders into bite size pieces, and put into a gallon Ziploc bag. Pour the buttermilk and Franks into the bag. Massage chicken in bag, refrigerate overnight. Mix dry ingredients(flour and seasonings) in a medium bowl, reserving 4 TBSP of flour mixture for later use in gravy. Whisk the 3 eggs in a bowl. Pour oil into skillet, until about 1/2 inch deep. Heat on medium high until it reaches 350 degrees. Drain excess liquid off of chicken. Dip small chicken pieces (in small batches) into the flour mixture, then into egg, shaking off excess egg, and back into the flour. Place gently in oil and fry in small batches until chicken is done, turning once to brown evenly. Once chicken is done, remove to a cooling rack over a cookie sheet, and place in oven heated to 175 degrees to keep warm while you make the gravy. For the gravy, drain off all but 1/4 Cup of the oil in the skillet. Turn heat to low, add reserved flour mixture to oil, and whisk until oil and flour is mixed well together. Whisk in the chicken broth, bring to boil on medium heat, then lower heat to low, and simmer (whisking constantly) until it thickens. Once it begins to thicken, add milk or cream, to desired consistency (You may not use all of the milk/cream). Add salt and pepper to taste.
