Step 1

Place the vinegars, water, sugar, and salt in a jar with a tight fitting – shake lid until well combined. Add the sliced red onions. Refrigerate at least 24 hours or longer for best flavor.

Step 2

Place the vinegar, olive oil, sugar, pepper, and salt in a jar. Crush the garlic clove and just drop it in the jar in one or two pieces – the idea is that you’ll still get some fresh garlic flavor infused into the dressing without the little pieces of raw garlic in the dressing when you serve it. 🙂 Shake to combine. You can make this ahead.

Step 3

Toss the grapes and farro with about half of the dressing. Add the arugula, basil, cashews, and a handful (however much you want) of the pickled red onions. Toss to combine. Add additional dressing if it needs any more – for me, the original amount of dressing was just about right. Let the salad sit for just a few minutes to really get it nice and yummy, soaking in that dressing.
