Preheat your oven to 375°F (190°C) and prepare a baking sheet with parchment paper.

In a large mixing bowl, combine imitation crab, refried beans, cottage cheese, and Old Bay seasoning. Mix thoroughly for about 2-3 minutes.

Lay tortillas flat and lightly brush one side with oil.

Place a generous spoonful of the crab filling onto the un-oiled side of each tortilla. Fold and roll tightly.

Transfer chimichangas to the baking sheet, seam side down, and lightly coat the tops with oil.

Bake for 25-30 minutes until golden brown and crispy, covering with foil if needed to prevent burning.

Let cool briefly, then serve hot with salsa and avocado.
