Old Fashioned Macaroni Salad

I made this for a BBQ and I thought it was pretty good. As always I changed it a little. The original recipe called for way too much mayo, so I cut back. I used whole wheat macaroni. I also omitted the tuna and substituted 1/2 of the green bell pepper for 1/2 of a red bell pepper. I probably could have used less mayo still and cut back on the mustard. There is a link the the original recipe if you want it.
