First, cook the Italian sausage in a pan on medium heat for 5 to 7 minutes until it's all cooked. Then, put it on a plate with paper towels to soak up the extra oil and leave it there.
Next, heat up the waffle iron to medium heat.
Now, take the pizza dough and cut it into 4 pieces. Spray with cooking spray on the waffle iron and put one piece of pizza dough on it.
Quickly add some shredded mozzarella cheese, sliced pepperoni, chopped onion, chopped bell pepper, black olives, and the cooked Italian sausage.
Then add another piece of pizza dough on top. Close the lid and press it down for 30 seconds.
Let it cook for 6 to 8 minutes until it's crispy, and the cheese is all melted and bubbly.
Finally, take it out and let it cool on a cooling rack. Enjoy your pizza waffles!
