This dish has a nice spicy kick. If you are really sensitive to heat, you can sub in green bell pepper for the poblano pepper and reduce the gochujang sauce to just 1 tablespoon. You may need to increase the salt then, as gochujang sauce has a lot of flavor in it. Make sure to use a creamy milk (like a high-fat creamy oat milk) and not a thin, watery one or the sauce will be less rich and flavorful. Avoid using full-fat coconut milk, though, as it is way too thick and will overpower the dish with coconut flavor.
