Saute the chopped vegetables in the butter and Old Bay Seasoning.
Add the stock, wine and tomatoes and simmer until vegetables are soft. Use less stock if you like a thicker bisque - one reviewer mentioned this was a little thin for her taste: no problem withholding, then adding some of the stock at the end until you get it the way you like it!
Melt the cream cheese into the stock/vegetable mixture.
Add the crab, heat and serve.
Note: I use Redi-Base seafood stock base, available on line.
