Not so much as making a salad, but more like buying "ingredients"!?!
On occasion, have bought sliced mushrooms. Loose ones looked a bit beat up and didn't NEED a whole package.
Not always available at SB, but when I see sun-dried tomatoes in olive oil, will buy some.
Yesterday found an interesting item. Supermarket usually has REAL bacon bits... have been told they make them in-house. Yesterday found something I had to ask about. Ended up being VERY thinly, basically shaved/chipped bacon... like flakes.
Didn't do any "math", but pretty sure bargain compared to alternative??
