How to Make It
Pick crabmeat, removing any bits of shell.
Heat 2 tablespoons of the oil in a small skillet over medium. Add breadcrumbs, and cook, stirring often, until toasted and golden brown, 2 to 3 minutes. Remove from heat, and set aside.
Heat butter and remaining 6 tablespoons oil in a large, deep skillet over medium-high. When butter starts to sizzle, add onion, artichoke hearts, oregano, garlic, Worcestershire sauce, bay leaf, cayenne, salt, and pepper, and cook, stirring often, until vegetables are slightly softened, about 5 minutes. Add wine and lemon juice, and cook until liquid reduces slightly, about 5 minutes. Add crabmeat, scallions, and parsley, and cook, stirring often, until crabmeat is warm and wine is mostly evaporated, 2 to 3 minutes. Remove from heat; taste and add seasonings as desired. Remove bay leaf. Cover and let stand 5 minutes. Transfer warm crab mixture to a serving dish, and top with toasted breadcrumbs. Serve immediately with bread slices.
