If you want to set this up in a mason jar, I would suggest using a smaller, but wide jar. You don’t want too tall & narrow or else it’ll be hard to get the fork in. If you don’t have a mason jars you can always layer this in a salad bowl. The other option is to have all the ingredients placed in separate bowls and have your guests build their own. You’ve got options.
One salad at a time, start with the spinach. Then layer a few spoonfuls of lentils and garbanzo beans. Stack slices of cucumber, and then add a handful of tomato halves. Top with fresh arugula.
In case there are any dairy allergies, you can keep the cheese on the side. If not, add the parmesan and some ground pepper – ties all the ingredients together nicely.
To make the dressing: In a small bowl, add garlic cloves, mustard, apple cider vinegar, lemon juice and mix together. Continue to whisk, while you pour in the olive oil. Season with salt + pepper.
When you’re ready, set out the mason jars (or salad bowl/s) and dressing in a container and guests can help themselves.
Serve and Enjoy!
