Lazy one-pot chicken & pasta

I had leftover chicken roast and sauce from a previous baked expedition all saved up for this quick bake. 

I threw in the usual dried herbs and half a head of garlic before adding the can of diced tomatoes. 

Once boiling, the pasta went in. 

I love my Aunt's trusty Rowenta oven. I can see everything cook:

It's looking pretty good. The sauce is getting thick while the pasta shells eat up all that herby broth. It tasted wonderful 30 minutes ago, it should be fantastic when it's done. 

Is that a gorgeous mess or what?
