Can you make a beef one? If so, I would just skip the tomato, beef sauce and just use the white sauce with chicken and layer with pasta as usual. You can add extra things like mushrooms, herbs,onions, ham etc..to the sauce and top with cheese.
I cook my chicken on medium in the microwave. I fry mushrooms and onions in a big fry pan, add chicken stock, cut chicken up into bitesize pieces, add to pan and mix all together. I then add black pepper and simmer for 5 mins. Layer the mix with lasagne sheets, cover with a white saucse, sprinkle with grated cheese and put into oven.
