Just so you all know, I used search before asking for help. But I couldn't find what I was looking for. Please help!

I need to find substitutions for two things:

Granola- I used to have grapenuts or granola with a little milk for breakfast. I'm one of those people who doesn't like meat for breakfast. I just don't find it appealing at all. I like my meals distintive, anyone else like this?
I like nuts so that isn't a problem but does a low carb granola exist? I mean one that fills you and tastes good? Is there a substitute for it?

The second thing
pasta- I make lots of meals that have sauces created from the cooking processes. I miss that third part to meals. I wish I had something for my tuna casserole or to put curry chicken on. What could I put stroganoff on (We've been eating it like soup) how about chicken with cream of mushroom? I have tried the low carb pasta and they are too strong in flavor or they are too chewy (tough?) Is there a substiture for this?

I would really appriciate any idea or thoughts, I've been low carbing over a year and having two teens hasn't made cooking low carb any easier. One of my differculties is getting my calories up to where it should be. Thanks!
