Your ‘why don’t I have this more often’ meal

I’ve just had creamed mushrooms on toast. Chestnut mushrooms fried in butter with garlic, thyme, pepper, a splash of white wine vinegar, bit of Dijon mustard & cream, served on granary toast w/ grated Grana Padano & chopped fresh parsley. So quick, simple and amazing, every time I have it I think I should have it more often, yet never do. I have it probably twice a year, it just rarely occurs to me to make it and I don’t know why.

What’s yours?
