The only way I can eat them is as follows
Take a hand full collard greens, or a mix of collard, mustard and turnip greens, and place them in a large cup
Add some sprigs of broccoli or broccoli sprouts
Add a couple of small carrots
Add a banana (to mask bitterness), strawberries and blueberries
Add several boost foods such as chia seeds, flax seeds, camu camu, maqui powder, macca powder
Add cocao nibs
Add a mix of chocolate and vanilla protein powder (to make the flavor tolerable)
Blend with a Nutribullet bullet, pour in a glass and serve.
That's how we rock collard greens in California.
