Baked mushroom rarebit

I think about food a lot. On my cycle rides to and from work. During "down time" at work. In relaxation at my yoga class. Before I go to sleep and when I wake up. I most enjoy thinking about food when I'm trying to figure out what to make for dinner, trying to remember what's in the fridge and mulling over the possibilities. This evening's cycle ride home saw me considering mushrooms, eggs, some taco shells, and old spring onions. The mushrooms were portobello, so baking them seemed in order. I could do an oniony omelette to go alongside, and maybe break the taco shells in half, sprinkle them with cheese, grill them, and dollop on some sour cream. So far so good. But what baked mushroom recipe? I turned to the trusty Interweb and came across this: Baked Mushroom Rarebit.

The mixture takes about 5 minutes to pull together:



And 15 minutes later, the mushrooms are out of the oven and next to an omelette. Oh yes, it's one to remember.
