So there are two ways to do it, the first one is quicker and easier, but requires an air fryer.

Air Fryer - Best kitchen appliance I've bought in years. See below.

So I cut trim the stem and split the spouts then toss with little olive oil and salt and pepper.

In the oven:
1) Preheat to 400 degrees
2) Lay them out on a cookie sheet.
3) Cook for 20 minutes, check and flip then if they are getting too brown about 35 minutes total

Airfryer:

Toss them in with the olive oil - and if you have the kind I do - it will rotate them automaticity. Cook for about 15 minutes.

You want them nicely browned on both sides but not burnt, obviously. You do need to watch them towards the end b/c they can turn fast.

You should only need enough oil to jeep them from being dry.

Once you have them cooked you can do all kinds of stuff with it in wok. I basically start the sprouts, then work on my additions as they are cooking.  I think the ones I did last time where:

- Pancetta bits (save the rendered fat to cook the Apples in)
- Add some minced garlic (it will burn easy so add towards the end) 
- Small cubed apple bits - cook in pancetta or a little butter until soft.
- Toasted pine nuts (toast in pan with no oil, once they start to get a little browned take the pan off the heat and keep moving them around - they also burn easy).

Then you can hit with a Balsamic Vinegar glaze. They sell it in any grocery store in the Vinegar section.

Once you get dialed in on the sprouts you can toss it with a lot of fun variations like:
- Fresh lemon juice instead of Balsamic 
- Red Onions
- Almonds or cashews.
- Grated cheese like Parmesan 
- Chili flakes
- Smoked Paprika
- Pomegranate seeds and honey
