The John Edwards (search) campaign is encouraging people to hold the mayo, forgo the ham on rye and brown bag it to work this Tuesday.

In lieu of going out for lunch, supporters are asked to donate the dollars saved to the Edwards' presidential campaign.

Requested donations for the "Official John Edwards Bring Your Lunch To Work Day" range from $5 — "leftovers from last night" — to $250, enough to feed the Edwards campaign field staff, according to the announcement.

Fund-raising categories also include $10 (soup and a sandwich) and $75 that would cover "a nice lunch for three."
