Salad bars can be pricey. Did I say 'can be'? Our local store is 6.99 a pound. But the salad bar can still be your friend.
Say you are making a salad that requires red onions, and you generally don't use red onions. It wouldn't make sense for you to pay for a whole onion only to let 3/4 of it rot in your vegetable drawer. But a spoonful from the salad bar will be just what you need, and because it is so lightweight it should be very cheap. (Way less than a dollar.)
I looked at the fresh mozzarella and tomato salad on the antipasto bar. Then I realized I'd be paying $6.99 a pound for cherry tomatoes. So I just bought a small container of the littlest mozzarella balls and headed to the regular vegetable area. A pint of cherry tomatoes costs $2.50, and as my father used to say "a pint's a pound, the world around." Really, it almost is...I actually weighed one, LOL!
So I'm making a caprese salad to go with the pasta we're having for dinner. My son is coming over. We've established Monday as our tradition to eat together. So I always make something he really likes. Actually, Mike makes the sauce. I'm just making the salad, which, as you can figure, is a pretty special treat for the price. Still, it's a lot cheaper than if I had bought tomatoes from the salad bar!
