I picked up a packet of Casserole Vegetables (pic attached) intending to make a veggie casserole- possibly in the slow cooker... but what do I actually do with them?!
I got veggie stock cubes, can I just put the veg and some veggie stock in the slow cooker? Do I need to boil the veg first? Does it need something else like a tin of chopped tomatoes in too?
I also got some veggie suet (atora) to make dumplings 
Thanks!
