This is a wonderful sandwhich from Pittsburgh. Trademark is french fries served on the sandwhich as a topping, with tomato, provolone and vinegar based cole slaw. Made famous @ "Primanti Bros" resteraunt. A family tradition in steel town.
Heres my take.
4 slices italian or sour dough bread, slice em thick, get a "tall" loaf if possible, these are serious sandwhiches.
4 slices, tomato.
1/4 head cabbage. Cut into very small strips (shred). Add 4 tablespoons vinegar, red cooking wine, salt, pepper. (optional, 2 tablespoons honey mustard)
1 big or 2 small Idaho potatos. Cut into fries. Deep fry. Drain, set aside.
2 hot italian sausages, cut in half, press so they would each cover most of the bread. Grill until cooked, when finished, melt provolone slices (1.5 circles each). (you can substitute any meat/fish/egg instead!)
Add sausage(or other)/cheese on botton of bread. Add french fries on top of cheese. (i add ketchup and or hot sauce on the fries), press cole slaw unto fries, top with tomatos, add other slice of sourdough. Cut sandwhiches in half, serve with fries/slaw that didnt fit.
