Spaghetti Napolitan: Japanese Style Spaghetti

I picked up a pre-made bowl of spaghetti Napolitan at a Japanese market near my apartment to try for lunch at work the next day and absolutely loved it.  It was so simple and delicious I wanted to try and make it myself. 


Ingredients:

1 package of spaghetti noodles, cooked to package directions.  I used a little less than the entire package.
1 bell pepper, thinly sliced. 
2 tbs chopped parsley
1 medium onion, thinly sliced.
1 clove garlic chopped
6 slices of ham sliced into squares, add more if you like,
or you can use sausage or hot dogs
2 tbs olive oil
3 tbs butter
4 tbs ketchup
parmesan cheese
1 tsp sugar
salt and pepper to taste


Directions:

1.  Cook spaghetti according to package instructions.
2.  Saute garlic in olive oil and just before it turns brown, add onion and bell peppers and ham
3.  Cook until slightly softened, about 3 minutes
4.  Add ketchup and 1/4 cup of the boiling pasta water
5.  Add sugar and salt and pepper to taste. 
6.  Add pastam butter, some parmesan cheese.
7.  Mix everything well and add more of anything to your taste.  I couldn't accurately measure what I used exactly.  Top with parmesan cheese.
