When I was a newly wed, we visited some relatives in WV and she made this macaroni salad and I thought it was one of the best things I ever tasted (macaroni wise). I always make this with 4 cups, and it makes a HUGE amount! I filled a 14 cup bowl and a 5 cup bowl with this. You could easliy make it with 2 cups of macaroni and have a good amount. I don't measure the tomatoes and cukes or onion, just how ever much I want to put in there. Hope you like it!
