Gestational Diabetes Salad Nicoise Sandwich

Tuna Nicoise Sandwich

Servings: 2 people
Carbohydrate Serves: 2 per person
(1 carbohydrate serve = 15 grams of total carbohydrate)

Sometimes making a tasty gestational diabetes friendly lunch is as easy as putting your favourite salad into a sandwich! The only trick here is to mix some of the salad ingredients with the dressing to make your sandwich extra juicy. Add some chili to your dressing for an extra kick or try the alternative serving suggestions at the end of the recipe. Enjoy! (Main carbohydrate containing ingredients are listed in bold.)


  • 1 tablespoon extra-virgin olive oil
  • 1 tablespoon white wine vinegar
  • 1 tablespoon Dijon mustard
  • 1 x 185g/ 6 ounce canned tuna in saltwater, drained
  • 1 large cucumber, sliced lengthways
  • 1/2 small red onion, finely chopped
  • 2 multigrain bread rolls
  • 2 tablespoons jarred black olive tapenade
  • Salad or rocket/ rucola leaves
  • 1 cup fresh basil leaves
  • 2 hard-boiled eggs, sliced
  • 1 large tomato, sliced in rounds

In a medium bowl whisk together olive oil, white wine vinegar, Dijon mustard and season with pepper. Put 2 tablespoons of dressing into another bowl and toss with tuna. To remainder of dressing add cucumber and red onion and toss. (I find mixing some of the ingredients with the dressing makes for a juicier  sandwich.)

Cut open bread rolls and build sandwich on the bottom half. Start with a layer of tapenade, some salad leaves, basil leaves, 1 sliced egg per roll and tomato. Top with tuna, cucumber mix and close tightly.

Serving suggestions: This sandwich is also great as a wrap or as a toasted, open wholegrain sandwich. And if you like it hot, mix some chili flakes or paste into the dressing.
