Notes
You can store this salad in the fridge for up to 4 days. Simply cover the mixing bowl with plastic wrap or transfer it to an airtight container.
Remember to rinse your veggies before chopping them to wash off any dirt.
Each head of broccoli and cauliflower will weigh about one pound. You’ll want to make sure you have about 3-4 cups of both chopped broccoli and cauliflower.
If you don’t have any apple cider vinegar you can use red wine vinegar. Apple cider vinegar has a slightly sweeter flavor while red wine vinegar is a little more tangy.
You can replace the walnuts with almonds, pecans, or simply omit them.
You can add chopped bacon, onion, or even dried cranberries to this recipe if you'd like.
