Brown the ground beef in a medium saucepan over medium-high heat, breaking apart the meat into small pieces as it browns. Sprinkle with salt and pepper while cooking, then drain the excess fat.
Mix in the greek yogurt, bacon bits and cheese and add the ranch dip seasoning slowly, starting with 1/2 of the packet. Stir well until thoroughly combined.
Taste the mixture then begin adding more of the seasoning packet as needed to increase the tang of the ranch flavor. Sprinkle with additional salt and pepper to taste, garnish with some extra bacon bits and serve warm with tortilla chips.
