I'm a bit confused but if required my lasagne goes something like this:
fry onions, add peppers, mushrooms, courgettes, carrots, anything else you like, fry all together.
add paprika, pinch chilli, squirt tomato puree, random mixed herbs, large truckload of black pepper, shake of sugar and dash of lemon juice, crushed garlic and salt and mix through while frying over lower heat
add tin tomatoes and stir in spinach leaves.
layer with pasta sheets and bechamel, bake, voila
made up recipe but v yummy, sorry left-handed typing - bfing!
