Mushroom omelette - you can adjust the relative proportions of mushrooms and eggs, depending on your tastes / what's in store. Admittedly, I don't eat nearly so many eggs, now that I no longer live in same house / garden as our ducks.
This paragraph really does contain recipes that involve mushrooms 🙂
I'm just back from 4 days nordic skiing in Scotland, with nights in a climbing club hut, so meals were a mix of whatever people brought with them / bought locally (by the way, Morrissons in Fort William may lose some sales to the new bigger Co Op that opened in Ballachulish this week). First night I was still travelling. Second night (for 4 people) was 3 packs of mushroom risotto mix (supposedly each for 2 people, but not people who'd spent all day ski touring in Scottish conditions 🙂), with added fresh mushrooms, garlic, cherry tomatoes, broccoli, and pasta sauce. Third night (for 5 people) was based on the gnochi and pasta sauces I'd brought, along with more mushrooms, garlic, tomatoes and broccoli. Fourth night, 2 Japanese climbers offered a lift to Clachaig Inn, Glencoe to a doctor from Edinburgh, the volunteer hut warden from Brighton and me. I had my normal meal in a Scottish pub of haggis, tatties & neeps, and it was one of the best ever, good value, too. Real ale selection was good, too, so each non driver had a different pint and tasted each others. We felt the Japanese climbers (one of whom has lived in UK for about 10 years) should try Irn Bru, so bought them a can - they didn't finish it!
