Start by browning your beef and draining. Add one cup of pizza sauce to the pan and set aside.
Spray crockpot with cooking spray and add 1/2 cup of pizza sauce to the bottom of the pan. Then add half the bag frozen ravioli, half of the browned meat, half of the pizza sauce, and top with half of the cheese. Then add veggies.
Repeat that second layer again on top finishing with cheese and toppings and then place lid on the crockpot.
Cook on low for 4 1/2 hours until melty and then serve.
