Ok so we all know about fake meat products. They are all some weird smashed soy stuff with food coloring (or in the case of Quorn: mycoprotein translates into fungal sludge). I know, I eat the stuff and I genuinely like it. However, I like this better: real food. This is how I made fake tuna sandwiches out of real food.
Combine equal proportions of cooked chickpeas* and artichoke hearts (canned or frozen but probably don't want do use marinated as it will change the taste and texture). Pulse in a food processor until the consistency is like tuna from a can. Then add other stuff you like: mayo, green onions, white onion, pickle relish, lemon juice, salt and pepper for me. You could do it like a chicken salad too and add grapes and walnuts. Get creative. Then I just spread it on some nice sourdough bread with crisp romaine leaves and ripe tomato. It hit the spot. It has protein like tuna and a lot of fiber. I served it with an Israeli couscous asparagus salad on the side.
**For this recipe you could also use white beans.
