This dish is essentially like making a cauliflower cheese but using other vegetables instead, and topping with breadcrumbs, herbs and cheese. You could instead substitute the breadcrumbs for a flour and butter mix (like a savory crumble without the sugar); I was going to do this and then realised I had no flour, but the breadcrumbs were a nice alternative. My choice of other vegetables was dictated by those that were reduced in the supermarket, so by all means use other vegetables if you prefer. Essentially you cook all the veg and mix with a cheese sauce, before topping with breadcrumbs and more cheese. Yum. I served this with plain boiled potatoes but you could serve it with a simple side salad or anything else you fancy. I never measure out my butter/flour/milk when making a cheese sauce, so I've estimated it - you might want to keep an eye on how much milk you put in. Note however you can always thicken it up with more flour (just make sure you whisk it in to avoid lumps) or loosen it with milk.
