In a food processor, combine the cottage cheese, shredded Mexican style cheese, shredded fat-free cheddar cheese, sliced jalapeños, skim milk, taco seasoning, cheddar powder, garlic powder, and salt. Blend until the mixture is smooth.
Transfer the blended mixture to a microwave-safe bowl. Heat it in the microwave in 45-second intervals, stirring in between, until it is thoroughly heated.
Once heated, stir in the cooked ground beef and the diced tomatoes with green chilies, ensuring everything is well mixed.
Serve the dip warm with protein tortilla chips or nachos.
