This recipe takes a healthy vegetable & completely runs it. First you boil it in lots of water & throw out the nutrients when you drain it. Then you smother it in unhealthy saturated fat in the form of coconut milk & coconut oil. You can make delicious dairy-free & a lot healthier creamed greens by making a basic white sauce with unsweetened almond, or cashew milk.
Methinks you'll need a lot more than a shallot for seasoning to lift this recipe out of the bland, bland, bland department! Spices DESPERATELY needed.
