Hotdogs, hamburgers, I like a little Shepherd's pie with my ketchup, tourtière (Quebec mince pie).

Fresh used napkin and tissue squeezings. Bonus points if the user had a cold.

Hmm, I put ketchup on scrambled eggs in the morning.

Macaroni casserole and hot dog

Pasta

I used to mix it in with fried rice that'd been left sitting out for too long and turned really dry. Gives it some moisture and a vinegary edge, but probably not for everyone, since ketchup's trademark is stomping all over the subtle flavors of a dish.

When I was in elementary school, I'd dip my pizza crusts in ketchup at lunchtime. I still do that every now and then with Sriracha ketchup

Also, same elementary school lunch: on pizza days, they also used to give us a side of tricolor fusilli straight-up. Just plain pasta without even so much as a little olive oil. So, fuck it. It got blasted with 'chup.

Hotdogs or eggs.

Haha ye old reddit fuck you

Hawaii pizza.

And plain leftover rice along with mayo.

Mayo. But honestly I don't eat it for the fries, I would chug mayo if I could

Mustard. Mustard. Mustard.

Ketchup and fries isn't even that good. Mustard and fries is where it's at.

Samurai Sauce. Kinda like flavored mayonnaise.

Ranch
