Toast the bread if desired.
In a shallow dish add chickpeas, avocado, and mash them together with a fork.
Add in the cilantro, green onion, tuna, lemon juice and zest, sea salt and pepper to taste, then stir until well combined.
Spread about 1/3 cup of mixture onto each slice of toast, then cut in half + smash together nicely, and arrange them in glass containers as shown. In the remaining space add in 1/2 cup berries into each.
Refrigerate for up to 3 days. Enjoy!
