Thanks for the suggestion - it's really a Catch 22, so to speak. Your dish would still fit in a forum already listed. Searching then would become even more complicated. The forum Michael mentioned might be of benefit, as mentioned, you list your ingredients on hand and people offer suggestions. If, however, you have left-over roast beef you can simply ask in the beef forum for suggestions.
