1. **Mix Ingredients**: In a large bowl, combine the flaked salmon, breadcrumbs, onion, bell pepper, mayonnaise, beaten egg, Dijon mustard, salt, and pepper. Mix well until all ingredients are combined.
2. **Form Patties**: Shape the mixture into patties, about 2-3 inches in diameter.
3. **Heat Oil**: In a skillet, heat about 1/4 inch of oil over medium heat.
4. **Fry Patties**: Carefully place the patties in the hot oil, cooking for about 4-5 minutes on each side or until golden brown.
5. **Drain**: Once cooked, remove the patties from the skillet and place them on paper towels to drain any excess oil.
6. **Serve**: Enjoy your salmon patties with a side of tartar sauce, lemon wedges, or a fresh salad.
