Add the cheddar, hard-boiled eggs, cottage cheese, milk, green chiles and taco seasoning to a high-powered blender. Blend until completely smooth.
Add the pickled jalapeños and pulse briefly, just until they’re chopped and mixed throughout the queso.
Pour the queso into a cold pan, then turn the heat to low and gently warm it, stirring frequently, until warmed through. Do not let it simmer or boil. Serve with fresh veggies or your favorite tortilla chips and enjoy!
