This is the fastest possible dinner, and it manages to feel very luxurious with no effort at all.
Baked camembert fondue
Take a fairly cheap camembert. Wedge it into a dish just big enough to hold it, spike it with some slivers of garlic and put it in a 180C oven for 25 minutes.
While it bakes, prepare some fresh vegetables for dunking. We had some steamed baby carrots and lovely asparagus spears, but steamed broccoli or cauliflower florets would be lovely too. Or little new potatoes if you really want some comfort food.
Put the hot, garlicky melted camembert in between you and dive in with your fingers. If you run out of vegetables and have to wipe the remnants of the cheese up with a cube of bread, that won't be too great a hardship.
