A Whole Food Powerhouse Salad

It’s all about celebrating fresh, unprocessed ingredients that are bursting with flavour in my recipes. To help support a balanced diet to manage diabetes, it’s essential to know the nutrient breakdown of our meals.  In this tuna salad there is a great balance of essential nutrients, vitamins, minerals, and healthy fats.  Here’s a glimpse of the nutrient information for the ingredients in this Mediterranean Tuna Salad recipe:

  • Protein-rich tuna: Provides essential amino acids for muscle repair and satiety.
  • Salty feta: Adds flavour without excess sodium, I love to use feta as a seasoning replacement in my meals
  • Fresh vegetables: Red pepper, cherry tomatoes, cucumber and spring onion offer a variety of vitamins, minerals, and fibre to support stable blood sugar levels.
  • Olives:  Rich in heart-healthy monounsaturated fats and antioxidants
  • Chickpeas: Have a low glycemic index and high fiber content which both help to support our blood sugar control.
  • Greek yoghurt: Provides probiotics for gut health and protein for sustained energy.

Customising Your Feta Tuna Salad

The beauty of this healthy recipe lies in its versatility. Here are some ways to make it your own:

Add a Kick: For a touch of heat, include a finely chopped chilli pepper or a sprinkle of cayenne pepper.

Bean Power: Swap the chickpeas for white beans or even black beans for a slightly different flavour and nutrient profile. I love this tuna salad with cannellini beans. 

Veggies: Swap, add or exclude any of the diced vegetables to make this a salad completely to your preference. Change the spring onion for red onion or the colour of the peppers the choices are endless. 

Fresh Herbs: Add any fresh herbs you like or need to use up. try dill, chopped fresh parsley is one of my faves, or even a sprinkle of fresh basil.

Different Ways to Enjoy This Delicious Salad

This salad is incredibly versatile and can be enjoyed in several ways:

  • Simple Salad – Serve it on a bed of romaine lettuce for a light lunch or dinner.
  • Sandwich Spread – Stuff the salad into wholemeal pita bread or spread over wholemeal bread for a quick and filling lunch on the go.
  • Snacking Dip – this makes a super healthy dip to go with pita chips or corn tortillas
  • Pasta Salad – Mix in some cooked pasta of choice for a deliciously easy dinner
  • Healthy Dinner – Add a packet of whole grains such as cooked quinoa for a balanced and light dinner.

Storing any leftovers 

Here’s how to safely store any leftover Feta Tuna Salad:

Transfer any remaining salad to an airtight container. This will prevent bacteria growth and keep other fridge odours from seeping in. I prefer to use a glass container with a clippable lid as unlike with plastic the odours from teh fish can’t be absorbed into the container.

How Long Will It Last?

Leftover Feta Tuna Salad should stay fresh and safe to eat for up to 3 days in the refrigerator. However, it’s always best to use your senses – sight and smell – to determine freshness.

Diabetes Note

This protein-packed Feta Tuna Salad is a diabetic-friendly lunch option that ticks all the right boxes. The tuna and chickpeas provide a steady stream of protein and fibre to help regulate blood sugar levels and will help to keep you feeling satisfied. The healthy fats from the olives and greek yoghurt offer a great healthy kick and provide balance too.
