Assemble the Salad Jars: Divide the ingredients between two jars, layering in the following order: lentils (base layer), shredded chicken, cucumber slices, crumbled feta, and arugula (top layer). Ensure heavier ingredients are at the bottom to keep the arugula fresh.
Store: Seal jars with lids and store them in the refrigerator for up to 3 days.
Serve: Shake the jar gently before serving, or transfer the contents into a bowl and toss to combine.
Notes
More Flavor: Top with a dressing or pesto before serving.
No Jars: Add each serving to a bowl or container.
