You are serving yourself pasta and you have zero access to tomato sauce. All you have in your pantry is ketchup (catsup.) Would you eat the plain pasta, or add ketchup for flavor?
You have NO ACCESS to tomato sauce. You cannot leave to buy any, you cannot call a friend to bring you any, you cannot order any, you cannot make your own sauce, and any other bizarre loophole. It is what it is. What do you do?
At least one a year I go to a pizza joint while traveling and get pepperoni, jalapeno, and pineapple. I generally don’t enjoy the tradition Hawaiian (Canadian bacon and pineapple) but the jalapenos offset the sweetness of the pineapple, and pepperoni > Canadian bacon.
Jalapeños are absolutely what make pineapple pizze good. I do bacon instead of pep, but both would work
