We had something very similar. Did feel like F&C on the back lawn in the sun though...lack of funds won out though
DH cooked a piece of steak & chopped into bite size pieces, then he cooked chicken, chickpeas, spring onions.
This was put onto of macaroni pasta & then covered with a goats milk white sauce, to which I added parsley & salt to make it "cheesey"
First time we've used goats milk & it was really yummy!
Also if you are cheaping out on cheese sauce, just make white sauce & add in a teaspoon of salt...no one will know the diff!
