Saute diced Onion (1) and diced Bell Pepper (1) in a little oil until soft and turning brown. Set aside.
Into a mixing bowl, add Pink Salmon (1 can). Break it up with your fingers, removing any bones.
Add Egg (1) and mix well.
Add Kosher Salt (1/2 teaspoon), Ground Black Pepper (3/4 teaspoon), Dried Oregano (1/2 teaspoon), and Garlic Powder (1 teaspoon). Mix.
Add veggies and All-Purpose Flour (3/4 cup). Mix to combine.
Form mixture into 9-12 patties and place on a baking tray lined with parchment paper.
In a pan over medium-high heat, heat Cooking Oil (3/4 cup). Place salmon patties in and cook until golden brown on both sides, about 3 minutes per side. You may need to do this in batches.
Transfer salmon croquettes to a plate lined with coffee filters or paper towel to drain excess oil before serving. Serve warm.
