I looked it up and I only read bad things about it.
If you are looking for something close to a tuna sandwich, this may do it for you. This is a tried and tested recipe that I find extremely delicious... I made a few alterations to a version I found online. You may end up changing things around for yourself, depending on how you like your "tuna":
1 can chickpeas
1/4 cup Nayonaise (or other mayo you like), you can get away with less
1 tbsp lemon juice
2 tsp vinegar
2 tbsp pickle relish
1 tsp salt
Pepper to taste
2 large stalks of chopped celery
4 sprigs of chopped scallions (green onion)
Drain the chickpeas, but do not rinse them, so they retain some of that salty "canned" flavor.
In a large mixing bowl, mash the chickpeas and mayo with a potato masher until they are of desired consistency.
Don't use a food processor, otherwise you'll end up with something too smooth.
Mix in all the other ingredients.
It's best if you let it chill in the fridge before serving.
Can be eaten in a sandwich or in a wrap. Excellent with lettuce and sliced pickles.
I recommend a softer whole grain bread to go with it.
