In a large skillet, cook ground beef until browned and crumbly; drain.
Add taco seasoning, and follow package directions to season ground beef.
In a medium mixing bowl, beat cream cheese until almost fluffy; slowly add in salsa and mix well.
Take a tortilla, and spread a spoonful of the salsa mixture in the center. Spoon some ground beef on top of the salsa mixture (enough to cover the salsa). Top with cheese.
Fold the tortilla up as you would a burrito, and place onto a baking sheet.
Cover baking sheet with plastic wrap or foil, then place into freezer to flash freeze.
Once they are frozen enough not to stick to each other, transfer to an airtight container or gallon-size zip-top bag.
When ready to serve, preheat oven to 350℉. Place frozen pockets onto baking sheet, brush with melted butter and tent with a sheet of foil. Bake 20-25 minutes, or until steaming hot.
