Speaking as a citizen of a country where we regularly put canned spaghetti on pizza, my only objections to this are:

1. I don’t like baked beans

2. The spaghetti thing is only on homemade pizzas, particularly ones that are “pizza” on a bagel, an English muffin or a circle of pita bread, not a proper pizza dough base. No one buys a pizza with spaghetti on it, even a frozen one. We’re barbarians but we have boundaries.
