In a 2 litre microwave safe casserole dish, combine the broccoli and onion. Cover and cook for 1-2 minutes on HIGH (100%).
Add the capsicum. Cook for 30 - 60 seconds on HIGH (100%). Allow to stand for 1 minute.
Place the almonds in a single layer on a sheet of paper towel. Cook for 60 – 90 seconds on HIGH (100%), turning at least every 20 seconds. Watch closely to prevent burning. Set aside.
Combine the vinegar, oil, pepper, and salt in a small dish. Whisk for a few seconds to combine.
Just prior to serving, pour the dressing over the broccoli, toss and sprinkle over the almonds. Serve.
