Murdered Hotdogs

I remember eating and making this snack ever since I was a little kid. Making it my own by adding a few more ingredients, I've also discovered that aside from as an afternoon merienda, it also goes great with a bottle of cold beer.

Murdered Hotdogs
(Serves 1-2)

Ingredients
2-3 hotdogs sliced into small pieces (either all meat or red; doesn't matter)
regular ketchup
1 medium to large onion
hot chili/chili powder/hot sauce/red chili flakes (the more the spicier)
cooking oil
parmesan cheese (optional)

Directions
1) Heat the oil in a pan, and then saute onion and hotdog pieces.
2) Add some chili, keep frying
3) After around 2-3 minutes, add ketchup (about half a cup --more if you're big on ketchup) and chili
4) Mix together in pan til ketchup begins to simmer.
5) Sprinkle with a bit of parmesan and serve! :D
