you can make lasagne with quark on top instead of béchamel or fat free greek yogurt with a small amount of cheese on top. It tastes funny at first but you soon get used to it. I do roasted veg lasagne as I don't eat mince and am allergic to quorn.
roast off, aubergines, peppers, red onion, and any other veggies you might want o add. I do Mediterranean type veg as think it works better but my sister who's not keen on those does it with carrots, parsnips, beetroot etc. roast it with garlic and rosemary if you like it, a few squirts of fry light olive oil. when is cooked, layer in bottom of a dish, pour over some passatta, layer of lasagne sheet, then veg etc as you would a normal lasagne. top with the sauce in this recipe here or just fat free greek yogurt and a sprinkling of cheese. I use cheddar as prefer the way it melts to parmesan.
I used o try and stick to my meals being as syn free as possible and use my syns for treats such as mall choc bar or packet of crisps, or glass of wine/gin and tonic, so that I didn't feel deprived.
Warmer weather its much easier, as you can grill a piece of meat, adding dried herbs or seasonings and serve with huge salad, or veggies and then a bowl of fruit salad and fat free yogurt for desert. I freeze the yogurt in the summer and blitz with berries and its like ice cream.
I do find ti more expensive to shop for this type of diet though, but the pay of is worth it.
