Sautee some green beans and red onions in a little bit of Italian dressing and serve them on the side. The crunch of the veggies goes great with the salmon cakes
I know you've probably already made them but this is just for future reference...my mom used to make salmon patties all the time when I was a kid and she always served them with french fries (crinkle cut) and a lettuce salad which consisted of iceberg lettuce, green onion and tomatoes...toss it with mayonnaise ( I use quite a bit so its creamy)...I know it sounds a little off but trust me...all those flavors together are amazing...make it a little bit before ready to serve so it has time to sit and absorb everything
For as long as I can remember, my mom always fixes salmon patties, butter beans, and breaded tomatoes (canned tomatoes, spices, and torn up pieces of toast) together. I still request ask her to make me this meal!
