Slightly heat a wok or large skillet with 2 tablespoons of olive oil and add the chopped onions and grated carrots first.
After a few minutes, when the carrots start to soften, add the sliced zucchini together with the garlic, cook stirring for a total of 10 minutes.
Remove the veggies that have been cooking to another bowl, add an additional two tablespoons of olive oil, heat slightly.
Toss in the cabbage. Do not panic if the cabbage does not fit in, when cooked cabbage shrinks a lot, if necessary add in the cabbage gradually. Make sure to mix the cabbage from the bottom to the top to help the cabbage cook faster.
When the cabbage is cooked, put the other veggies back in.
Add the salt, red pepper flakes or spicy sauce, cumin and brown sugar and warm water to cover the bottom.
Make sure to mix occasionally.
Remove from the stove once everything is cooked as you like.
