1Line cookie sheet with waxed paper. In large bowl, mix egg, bell pepper, green onions, parsley, mayonnaise, seafood seasoning and mustard. Gently stir in crab meat and Swiss cheese. Season to taste with salt and pepper. Shape into 8 patties.
2Dip both sides of each crab cake into bread crumbs, pressing crumbs into cake with hands to completely cover; place on cookie sheet. Refrigerate about 20 minutes to firm up crab cakes.
3In 12-inch skillet, heat oil over medium heat. Add patties; cook until golden brown on both sides, being very careful when flipping so patties do not fall apart. Serve warm with tartar sauce.
