Make

Heat an oven to 425F (218C) degrees.
Toss sweet potatoes with oil and Cajun seasoning and spread into one even layer on a dark sheet pan (for better browning). Roast in the oven for 20 to 30 minutes, until crispy. Shake once midway through.
While sweet potatoes are roasting, heat a skillet or non-stick pan over medium-high heat. Add cooking oil. Once oil is heated, sear fillets in batches for 3 to 4 minutes on each side, until dark and golden.
Toast buns if you want to. Assemble sandwiches with fish, tartar sauce, lettuce, and tomatoes.
Sprinkle sweet potatoes with salt and pepper immediately out of the oven. Enjoy with ketchup and your fish sandwiches!
