If you’re cringing at the thought of a smoothie made with vegetables, you’re me even 5 seconds before I licked the spoon to taste this.

I genuinely had no hope of this turning out like the normal sweet nice cream or shake or smoothie coz there’s no banana or any fruit in here. But thankfully it actually did work out!

Yes, believe me. This was so good, I actually made it 2 days in a row, and only stopped because I ran out of zucchini.

How? The protein powder! It adds in all the sweetness, but without the sugar (or carbs) count.
