DO Fire Ring?

Well, Spring has come to MN...it's above freezing, the snow is almost gone, the grass is starting to have some green tint to it again...
...And it'll all end tomorrow! 7 inches of snow is what I heard, temps plummeting back to the single-digits by Sunday.
Oh well...Doing some planning for Summer anyway.
I'm thinking of doing my summer cooking outside, using a Dutch Oven among other things. If I were to build the perfect "fire ring" or "coal holder" or whatever you'd call it in my back yard for DO cooking, what would it look like?
If it helps any, I have a pretty good stack of bricks in my garage...took down the chimney when I reshingled last year.
Thanks!
David
