Drain and rinse chickpeas and dry well. Remove as many chickpea skins that you can because it will make the chickpeas smoother and the “tuna” a better texture. To do this simply mix the chickpeas lightly with your fingers and the skins will come off.
Peel the apple, and dice your apples into small pieces. You can leave the skin on if you prefer.
Add your chickpeas to a medium bowl and use a fork or a potato masher to mash them up until you just have a bit of chickpea chunks left.
Add mayo, raisins, salt, and apple and mix together well.
Serve on toast, enjoy with vegetables or crackers, or eat plain!
