My passion for niçoise salads and love for toasted bread have finally merged in a delightful creation: Tuna and Avocado Toast. This summer dish is a must-try.
Crispy bread layered with kale pesto, mashed avocado, crunchy cucumber, savory oven-roasted tomatoes, oil-packed tuna, and fresh basil.
Absolutely mouthwatering.

This incredible toast was inspired by my favorite dish at a local café in Austin, which I greatly missed during quarantine. I can't wait for them to reopen! The original toast was so good, I had to have it every Sunday. When it was taken off the menu, I decided to recreate it at home, and I think my version might just outshine the original.
To start, let's make the oven-roasted tomatoes. Toss cherry tomatoes with garlic, thyme (or rosemary or basil), salt, and a generous amount of olive oil. Roast them slowly until they caramelize and become sweet. I'd never made these before, but they quickly became a staple in my kitchen. I adapted the recipe from a well-known cookbook, and I store the extras in a mason jar for a month. These tomatoes are versatile and can be used in various dishes like pizza or sandwiches.


Good crusty bread is essential for this recipe. If it's a bit stale, that's even better for soaking up the olive oil and tomato juices. The combination of these ingredients feels luxurious, while still being healthy and fresh.
The vibrant green of the kale pesto adds a pop of color and is a fantastic way to use up leftover kale. I sometimes use store-bought basil pesto when I want to save time, and it works just fine. Now, let's talk about TUNA. High-quality oil-packed tuna is a game changer compared to the typical canned variety. It's a rich delicacy that transports me to a sunny terrace in the south of France. If you've only tried the lower-calorie options, please treat yourself to the good stuff—you won't regret it!
This Tuna and Avocado Toast is my go-to summer meal, and I've been enjoying it weekly. Give it a try and let me know how it turns out! Tag me on Instagram with your creations. Scroll down for the recipe...
