Kori's Tips

For more helpful hints, substitution ideas, cooking tips, and other delicious recipes check out my post above.
TIP: If making the low-carb version with cauliflower, cook the florets just until crisp-tender. Overcooked cauliflower can become soft and fall apart when mixed into the salad.
VARIATIONS: Substitute lump crab meat for imitation crab if preferred. To lighten the recipe, use light or fat-free mayonnaise and sour cream. For a low-carb or keto-friendly seafood salad, use cauliflower in place of pasta and a sugar-free French or Catalina dressing. Thousand Island dressing can also be used, but since it's sweeter, add a little ketchup to balance the flavor.
SERVING SUGGESTIONS: Enjoy this seafood salad on a bed of lettuce with a wedge of sweet melon for a refreshing summer meal. It also pairs wonderfully with grilled steak, seafood, or chicken and makes an excellent lunch or light dinner.
NOTE: Nutrition information is calculated using cauliflower and sugar-free Catalina French dressing. Values will vary if pasta or different dressing options are used.
