Slice spahgetti squash lengthwise and microwave for 5-7 minutes depending on the size of your squash.
While the squash is in the microwave, pan fry the beef for 1-2 minutes and then add about 1/4 of the sauce and let simmer while the squash cooks in the microwave.
The sauce will thicken and caramelize a bit (because of the brown sugar and sweet chilli sauce)
Remove beef from the pan.
Fry all of the veggies in a a couple table spoons of oil ( except the cabbage and squash).
Once the microwaved squash is cooled, scoop out the seeds and discard. Take a fork and pull the spaghetti squash flesh off the skin.
Once the other veggies are cooked, add the sauce, squash and cabbage until heated. Don't overcook!
Garnish with cashews (optional), green onions, and sesame seeds.
