Im griling mine with mustard powder and frylight, then eating them with syn free veg on a Red day and having 100ml Tesco gravy granules for 2 syns this evening!
I prefer them grilled plain with just a stirfry or mash & veggies, but I have slow cooked them before in a can of chopped tomato's with some chilli flakes which was nice.
If you don't have a SC you can casserole them in the oven the same way (whole).
