Prepare the dressing by placing all the ingredients in a small food processor or blender, and allow the mixture to emulsify. Divide the dressing equally between four jars.
Place the moist vegetables and firm ingredients in the second layer on top of the dressing, including the tomatoes and chickpeas. I would also recommend adding the avocado here so the acidity from the vinaigrette helps to slow down the browning.
Place the more delicate ingredients in the third layer, including the eggs and the blue cheese (if using).
Finally add the leafy greens on the top, including the spinach, romaine lettuce and parsley; then seal the jars tight.
To eat, just flip the jar into a large bowl and enjoy!

Notes
Storage: These salads will keep sealed in the fridge for 4 or 5 days. Keep them upright in the fridge so that the dressing doesn't mix with the greens.Equipment: These are my favorite mason jars (Amazon affiliate link) for meal prep. They are each 32 ounces, which I found to be the perfect salad serving size. And they come in a set of 4, which works well for Monday thru Thursday meal prep.Substitutes: For best results, follow the recipe as is. However the salad itself is very adaptable so feel free to add or change any of the ingredients.
