Heat the oven to 425*. Place pie crust in glass pie pan (prick bottom of shell),bake for approx 15mins.
Cook and brown beef (broken up into small pieces), onion, garlic in 10 inch skillet until brown; drain off grease. Sprinkle with salt and flour. Stir in pickle liquid, milk, pickles and 1-1 1/2 cups of shredded cheese (I use the package kind or grate my own off a block). Spoon into pie shell.
Bake 15 mins; sprinkle the rest of shredded cheese over top. Bake until crust is golden brown, about 5 mins longer.
