To give you an idea this is what I do to make it easier with grapes. This took me not even 10 minutes to do.
First I separate them from the bunch to wash & get rid of the grapes that aren't any good.
Making sure they are clean :) I use a solution of diluted vinegar (one part vinegar to three parts water) then rinse.
Then I measure out a serving, in this case 1 cup.
Next I put them in the snack ziplock bags. (Yeah, shame on me for using disposables but I do recycle them)
They go on a shelf in my fridge. Out in the open so I can just grab & go!
I also do this with string beans, broccoli, grape tomatoes, sliced cucumber, zucchini & pretty thing else that would fit in a bag.
Make it easy & the easier it is to stay on plan!
