Make Crab Mixture - Combine crab meat, 1 cup bread crumbs, egg, mayonnaise, mustard, salt, pepper, bell peppers, onions, and chives in a medium bowl.
Form the Patties - Divide crab mixture into four portions, about ½ cup packed or 4 ounces. Form into compact cakes, 3 inches wide and 1 inch thick.
Bread Crumb Coating - Add ½ cup of bread crumbs into a shallow bowl. Gently press and coat each cake.
Cook the Cakes - Heat a large nonstick saute pan over medium heat. Add vegetable oil and once hot add the crab cakes. Cook until the surface is golden brown and crispy, about 5 minutes on each side.
To Serve - Garnish with lemon slices or sauce of your choice.
