I enjoyed them as a kid, but as an adult, I only eat them once in a while. My mom, however, has suddenly taken a liking to them in recent years for some reason. They are tricky to eat, but the one thing I would always do is turn them upside down, so the crown of the bun was on the bottom. That lets the juices flow into the thicker part of the bun so the sandwich doesn't get too soggy.
Strangely, I prefer the canned variety of sauce over making it from scratch. It is a bit sweet, but every time I've tried to make the sauce from scratch, something always seems to taste "off" about it. Either the peppers will taste overly bitter relative to the sauce, or there might be too much of a given spice, or it just tastes like doctored up ketchup.
I think one of the reasons my mom, and perhaps other parents, enjoyed making these for their kids, was that it was also an easy way to stretch a pack of ground beef. Though you could more than likely make these with vegetable crumbles in place of the beef. It's really just meat in a tomato based sweet & sour sauce.
