For all the jar recipes I used wide-mouthed 32oz (946ml) glass Mason/Kilner jars. Always stack the ingredients from wettest to driest, with your greens at the top (unless otherwise stated). You can prepare a week’s worth of jars at the beginning of the week, or make them the night before. They will stay fresh in your refrigerator for about five days. When you’re ready to serve, simply turn the jar upside down and pour your salad out on a plate.
