Instead of pasta I use 2 cups chopped baby squash (Costco). Bacon cooks first. Drain pan and cook chicken. Remove chicken and add squash, mushrooms, one chopped leek. Cook until soft and add bacon, chicken, and cheese.
Roast pumpkin & spinach lasagne - have made this so many times (admittedly I cheat on the sauces) but it's absolutely delicious. I also add a layer of cherry tomatoes near the top, under the last layer of pasta. It makes such a difference.
