Yo. I just tried this that i found on the interweb. It sounds rank but its actually quite amazing.
Put 2 chicken breasts in a food processor with 1 egg white, salt n pepper and a bit of garlic.
Once it resembles snot smooth it out into a cake tin (about 1/2 inch thick) and oven for 20 mins.
Once its cooked, take it out the oven and drain the liquid. I also placed it on some kitchen roll to soak up the moisture.
Place onto a baking tray, Cover in tomato sauce, cheese and what ever you like and oven till the ingredients are cooked.
