In a large mixing bowl, combine the ground turkey, ranch seasoning, breadcrumbs, and chopped parsley.
Crack the egg into the mixture, adding a pinch of salt and black pepper.
Gently mix until all ingredients are well combined. Don't over-mix as it might make your High Protein Ranch Turkey Burgers tough.
Divide the mixture into two equal portions and shape them into patties.
Heat a non-stick skillet or grill over medium-high heat.
Once heated, place the patties onto the skillet or grill. Cook for 5 minutes on one side.
Flip the patties and cook for another 5 minutes on the other side. If you're adding cheese, place a slice on each patty a minute before they're done.
Toast the whole wheat buns for a minute or two until they're golden and crispy.
Assemble your High Protein Ranch Turkey Burger by placing a lettuce leaf on the bottom bun, followed by the turkey patty, then tomato and avocado slices.
Top it off with the other half of the bun and voila! Your burger is ready to be devoured.
