Make the Marinated White Bean Salad: In small bowl, whisk together garlic, vinegar, thyme, lemon zest, mustard powder, salt, black pepper and red pepper flakes. While whisking, slowly drizzle in oil until all oil is incorporated. Add beans and toss to combine.
Divide Marinated White Bean Salad equally among 4 pint-sized mason jars. Layer onion, tomatoes and arugula, ending with arugula. Top with lids and refrigerate up to 3 days. To serve, pour onto plate or bowl, stir and enjoy.
Notes
Instead of mincing your garlic with a knife, feel free to grate it on a microplane if you have one. You’ll have the microplane out anyway for the lemon zest.
If you don’t have dry mustard powder, a teaspoon of prepared Dijon mustard can be used.
Use a really good olive oil, as you will taste it in the prepared dressing.
