Could you do like a chilli with quorn mince?
I've never had it, but i loveeee chilli con carne, so maybe could be a substitute? I guess the sauce itself isn't so healthy though haha!
Also just a thought, going off the quorn mince totally but have you tried the dahl lentils in the cambridge book? I think its on the 810 plan not the SS+ section, but i do SS and ive made it a couple of times and still lost weight every week lol.. its beauuuuuutiful, especially if you like curry! Great to have on a saturday night
