Preheat your oven to 350 degrees F. Always preheat for a good 5 to 10 minutes to let the temperature rise then even out.
Spray a 9 x 13 pan with non stick spray generously. Set aside.
In a large frying pan brown your ground beef. You want to cook it until the juices run clear and it's browning. But don't overcook it. Nothing worse than overcooked ground beef, it won't absorb sauces well like that. Make sure you stir it often and break it up into little pieces.
Once the ground beef is cooked to perfection you can add both cans of the Manwich. Let it get to a nice bubble, then turn it down to a simmer.
Open the first package of Pillsbury Garlic Crescent Rolls. Unroll it and place it in the bottom of the pan you set aside earlier. Spread it out with your hands till it fits the bottom really well.
Now take half the mozzarella cheese (2 cups worth) and toss it on the dough evenly. Spread it out nicely.
Turn off your burner for the Manwich. Carefully pour the Manwich mixture over top of the cheese. Spread it out with a spoon evenly.
Now take your remaining mozzarella cheese (2 cups) and toss it evenly over the Manwich mixture. Spread it out nicely.
Now open the second package of Pillsbury Garlic Crescent Rolls and unroll it. The top is trickier. Spread it out by hand in sections before placing on the top of the cheese. You could press it down on parchment if you're uneasy doing this, then just flip the parchment over and the dough will drop over the casserole perfectly. Honestly it doesn't have to be perfect. I left some gaps on the side and it looks sort of cool when you do that. You get to see the cheese get all bubbly.
Place in the oven and cook for about 10 to 12 minutes, depending on your oven. You want the top to be golden brown.
Remove from oven and place on a secure surface.
Take a knife and cut the casserole into squares.
Remove carefully while hot, the first piece is always the hardest. May the force be with you for that one.
Serve with a big old sloppy joe smile!
