This lunch is packed with creamy avocado, protein-rich tuna, and loads of greens, making it fresh and nutritious. Sometimes, the simplest swaps make the biggest difference—like trading mayo for creamy avocado.

Say goodbye to mayo-heavy tuna salad! This fresh and healthy version combines tuna with creamy avocado, crunchy celery, spring onion, pickle and fresh dill, all brightened with a touch of lime. It’s easy to make and packed with flavour; the kids love it! Sometimes, the healthiest swaps are also the most delicious ones.
Why Avocado Is the Ultimate Mayo Swap
Looking for a healthier alternative to mayonnaise? This quick comparison shows how avocados compare in nutrition. Avocados are naturally rich in fibre, potassium, and heart-healthy fats, with zero cholesterol, making them a smart swap.
| Nutrient | Avocado | Mayonnaise |
|---|---|---|
| Calories | 160 | 680 |
| Total Fat (g) | 15 | 75 |
| Saturated Fat (g) | 2.1 | 11.5 |
| Fiber (g) | 6.7 | 0 |
| Protein (g) | 2 | 1 |
| Vitamin E (mg) | 2.1 | 3.3 |
| Potassium (mg) | 485 | 20 |
| Cholesterol (mg) | 0 | 42 |
While mayonnaise is higher in calories and saturated fat, avocado offers a lighter, nutrient-dense option with a fresh, buttery texture that kids and adults can enjoy.
Choosing The Right Avocado

Choosing the perfect avocado is simple with the proper technique. Look for fruit that yields to gentle pressure but isn’t mushy; it should feel like a ripe peach with just a little give. Here’s a pro tip: gently remove the small stem at the top; if it comes off easily and reveals green underneath, it’s perfectly ripe. If it’s brown underneath or won’t budge, pass on that.
Baby Led Weaning Version
Making this avocado tuna salad toddler-friendly is all about fun, bite-sized portions that little hands can manage. Spread the mixture on small pieces of toasted bread cut into squares, triangles, or even fun shapes with cookie cutters to make mealtime exciting. The creamy texture and mild flavours make it perfect for tiny taste buds, and the bite-sized format encourages self-feeding while keeping cleanup manageable for parents.
