Its not quick quick but it requires very little effort beyond the veg prep, clears out the veg box and creates minimal washing up
Slice potatoes (about the thickness of a pound coin) and place in a single layer in a roasting tin. Put in oven at 200 degrees for about 10 mins (until they are starting to crisp).
Add well seasoned chicken thighs (I add dried thyme or oregano too), a quarted lemon and an assortment of chopped longer cooking veg (broccilli florets, onion, celery etc) Cook for another 20 mins. Add 300ml liquid (I usually use 100 ml wine and 200ml stock) and any faster cooking veg (sliced mushroom, pepper, radishes etc. I often add sliced garlic too) Cook for another 20 mins.
Eat!
If you make double quantities, you can reheat leftovers the following day but cover tin in foil and add a little extra stock.
