I saw Jamie Oliver on TV once, and he said the best thing to do is to forget the so-called "Low Fat" products, as they are usually bad for you in other ways, and instead choose things that are naturally less fat, but good quality products that haven't been messed with.
I've found that you can just tweak the things you currently make to make them a bit more healthy. For example, you can switch from beef mince to pork, chicken or turkey mince. I've used pork mince for a while and it's much tastier and so much healthier.
When I make something like a curry or a chilli, I now add less meat and add a variety of vegetables. This usually means I have extra to freeze for another day. Mushrooms and courgettes are fab in a curry. Also, I've discovered that if you microwave a garlic flavoured pitta bread, it's a very good healthy substitute for naan.
Fajitas are a good healthy option as well, especially if you use chicken, turkey of prawns. Just really stuff them with loads of home-made salsa and salad...yummy!
Try doing different things with your meat, like making kebabs with different meat and veg. Another thing I like to do is cook a chicken breast in the oven with a tin of pineapple, which I'd definitely recommend you try.
Good luck with the healthy eating
