Layering here is very crucial for the salad to remain fresh.
- First layer: at the bottom of the jar, put the dressing: 1 Tbsp olive oil, vinegar, salt and pepper with any herb or spice you fancy: oregano, rosemary, peppermint, sumac... It is important to avoid mixing this bottom layer with the remaining of the salad (especially the green leaves and sprouts) until just before serving.
- The second layer should be hardy vegetable that will withstand being in the oil/vinegar dressing for 2-5 days. Basically any vegetable that can be pickled is good to add here: baby carrots, cherry tomatoes (whole not cut), zucchini, turnip, sun dried tomatoes...
- After that comes any other still hard vegetables (cucumber, celery, broccoli, cauliflower...), beans or fruits (pomegranate, cranberries -fresh or dried),
- Following layer is the protein. This could be animal-based protein like left over chicken, veal, tuna, salmon, smoked salmon, shrimps, eggs... Or, plant-based protein like lentils, beans, quinoa, nuts and seeds.
- you can still add perishable vegetable on top of that if you have place: cut tomatoes, bell pepper, avocados...
- the final layer should take at least 1/3 of your jar and this should be the green leafy vegetables and some sprouts if you want.
At time of serving you can just put the jar upside down for 2 minutes for the dressing to infuse the whole salad. Then eat straight from the jar. Or, you can empty the whole thing in a big bowl. Mix and serve.
Bon Appetit.
