You could include oats, under 5% in about any beer to add to head retention. I've done Ordinary Bitter recipes of 95% Maris Otter malt and 5% oats that have come out fantastic.
APA, American Amber, Irish Red, American Stout etc...
Maybe a cream ale with oats instead of corn... that could be interesting.
Or, you could make oatmeal for 100s or cookies! Why get 20lbs of Minute oats? I buy the Quaker Quick Oats at the supermarket and just use that for breakfast and brewing. *shrug*
