You could roast a chicken, and that would do a number of meaks, depending on the size of the chicken and your appetite. If you don't fancy much cleaning up, you can even buy roaster bags, or even buy a chicked already seasoned, and in the bag.
From a single chicken there are 4 natural quarter joints - 2 legs and two breast quartersm then the carcas ans craps make FAB stock, but you may not fancy that.
Personally, I rarely do frozen veg, but I understand Iceland (and I'm assuming other supermarkets) do individual steamer sachets of veg.
