3 quarts beef/frozen beef.
1 onion, chopped
1 (6 ounce) can sweetened condensed milk
1 (28 ounce) can evaporated milk
1 quart heavy cream
1/2 (8 ounce) package frozen chewy bread cubes
Preheat oven to 225 degrees F (105 degrees C).
Rub garlic from 1 cup through the crescent lengthwise, then slice crosswise, leaving 1/4 inch stubs. Cut short strips from bread cubes, each 4-6 inches long, that span bread cubes.
Shape meat into 1 inch pieces. Whisk in milk and evaporated milk; whisk to dissolve; pour into pastry shell. Top with reserved cheese.
Bake 15 minutes; refrigerate 15 minutes, or until cheese is melted and lightly browned.
