just buy pizza dough, tomato sauce, mozzarella and toppings of your choice and make a fresh pizza. Takes 2min to prepare. It's healthier and tastes much better.
For an extra ten or 15 minutes of active time, you can make the dough and sauce from scratch. Dough is definitely a bit more work, and requires a few hours of rising time and all that, but sauce is really easy - take a can of good tomatoes, blend it up, add salt, and that's all you need. You can add herbs/spices or sugar or tomato paste or whatever else to customize it if you want, but just tomatoes and salt will go a long way.
