This had delicious flavours and everything about it seemed 'just right'. We don't have semi-dried tomatoes (have never actually seen that term in a recipe before), so I used sun-dried, which we love. A keeper.
I made this without the olives, tomatoes, egg plant and basil leaves as I made other antipasto to go with just these marinated mushrooms. They were the best, my whole family loved them. Very easy to make as well. I made them the day before so they marinated for 24 hours so the mushrooms were very tender. I had balsamic vinegar in the pantry so I used that instead. Absolutely beautiful.
