Grease waffle iron with butter and put one bread slice over it. Now spread pizza sauce and arrange chopped vegetables including onion, green bell pepper, sweet corn, tomato and baby spinach over it.
Add mozzarella cheese over the bread slice. Now, sprinkle black pepper powder and dried oregano leaves. Cover it with another bread slice.
Cover and cook it for 5 minutes or until it turns golden in colour.
Repeat the same process to make more waffles. Bread Waffle Pizza is ready to serve with dips.
