Ingredient list for sauce: butter, flour, beer (dark), heavy cream, Dijon mustard, Worcestershire sauce, aged sharp cheddar. Will also need sourdoguh bread, 1" thick slices toasted.
For the stewed tomatoes, combine dice onion, garlic, red pepper flakes, and olive oil with grape tomatoes, sugar, fresh parsley, salt and ground black pepper
Top bread with cheese sauce and put under the broiler. Should be more brown than this, next time I'll leave it in longer. I couldn't resist the smell and was ready to eat!
