Gently toast the almonds in a dry skillet/frying pan or under a broiler/grill. Keep a close eye on them so they turn golden brown but don't burn then set aside to cool.
Peel the outside layer off the chioggia beet then carefully make thin slices with a mandolin or wide vegetable peeler. Try to make as complete circles as you can but even part slices are good.
Place the arugula on two plates and top with the slices of beet, crumbled goat cheese and the toasted almonds.
Shake together the vinaigrette ingredients (oil, vinegar and maple syrup) in a small jar or whisk in a small bowl. Drizzle over the salad and serve.
