I too am also am cr@p in the kitchen, but this one is quite easy, obviously if I'm cooking it.
Right, he goes - This is my own concoction.
I make enough for two (Dh is also subjected to my diet)
I use a small loaf tin, it just happened to be in the kitchen cupboard, but is about an inch bigger all round than the lasagne sheet.
Boil for 8-10 mins,2 peeled chopped carrots, 1/2 a peeled diced sweet potato, a few sprigs of broccoli and cauliflower.
Fry up your quota of minced beef (from healthy extras) (x2 in my case)
Meanwhile (this is technical) open a big tin of tomatoes with added garlic. When the veg are cooked add a couple of chopped mushrooms and the cooked mince.
Cover the bottom of the loaf tin with a thin layer of tomatoes, add a lasagne sheet and some of the veg mix. add another thin layer of tomatoes, a lasagne sheet and veg. when you have finished layering add another lasagne sheet, open a big tin of low fat macaroni cheese and put that on top. Cook in the oven (200 oC ish) for 30 mins.
