Tuna, egg and avocado sandwich with a tahini, miso and black garlic sauce

Constructing a sandwich is one of my greatest pleasures in the kitchen. I am a sandwich girl.



I don’t like going overboard or adding too many ingredients; I want to taste each of them and not get lost in a huge quantity of any single one.


I’m also a tuna girl. Give me a tuna sandwich and I’m the most satisfied person in the world. And even though no one can beat the simple tuna-mayo combo, this tahini and miso sauce with black garlic will be your go-to for all your sandwich needs, not just for tuna sandwiches. Because what can make or break a sandwich is the sauce, which needs to be as good as the bread and as good as the main ingredient, if not better.



In this sandwich, we have tuna, rocket, boiled eggs and sliced avocado on good sourdough, multigrain bread, with the most delectable, full of umami, earthy sauce. Rich and creamy, with salty miso and buttery tahini, with the caramel-y, balsamic flavor of black garlic, the freshness and acidity of the lemon and the fruitiness of the extra virgin olive oil, it is such a perfect combo.

The sauce is not too thick, so it can be easily spreadable on toast for a sandwich, and it can of course be used in an array of salads.

It pairs beautifully with beef, as well as with chicken, and of course with vegetables. Oh, and give me a piece of salmon with this sauce and I’m in heaven.


Yield: 4 sandwiches



for the sauce

90 g tahini

1tsp white (shiro) miso

2 black garlic cloves, peeled

4 Tbsp freshly squeezed lemon juice

¼ tsp sea salt, plus more if needed

Black pepper, 3-4 turns of the pepper mill

4 Tbsp extra virgin olive oil

Iced water, as needed

for the sandwiches

8 slices bread of your liking, I use sourdough or multigrain

2 handfuls rocket leaves

4 boiled eggs, halved or sliced

2 small avocados, sliced

1 can tuna in olive oil, drained

Lemon juice

Salt & pepper

Olive oil


Special equipment: stick blender (or regular blender)



for the sauce

In a large jar or large measuring jug to avoid splatter, add the tahini, miso, black garlic, lemon juice and salt, and using the immersion blender, blend everything until smooth. Then, add the olive oil in a low and steady stream, blending continuously, until it is completely incorporated. Add some ice water, one teaspoon at a time, until you have a spreadable sauce that is a little more runny than mayonnaise.

Taste and add more salt if needed.

You can store the sauce in an airtight container in the fridge for a couple of days.


assemble the sandwich

In a bowl, add the tuna and 2-3 tsp of the sauce, and mix with a spoon.

On one slice of bread, add a few avocado slices and sprinkle with salt and pepper. Then add some of the tuna and squeeze a little lemon on top.

Add a few rocket leaves, boiled egg, salt and pepper again, some extra sauce and finish with a little olive oil. Top with the second slice of bread and enjoy!
