OK I'm a little confused. Your OP said no pasta no cheese no tomato & lasagne is full of all those, yet you still managed to eat it.

You could try tuna parcels. 1 small can of tuna, 1 puff pastry sheet, mayo & chopped onion (can't remember if that's on the no list).

I think you need to see someone about your food issues though. It's not good for you to continue like this, not good for the pregnancy & will certainly not be good for your children to grow up with a mum who has so many issues with food.... they will grow up with food issues too. I avoided lots of things during pregnancy but I could still eat a good variety of food.
