recipes for green smoothies ?

If you are doing sugar free , which to me means fruit free too .. than does anyone have some ok tasting veggie smoothie recipes ? I at some points was doing cucumber , kale , carrot , beet , stuff like that , but I wonder if there are certain combinations that are more paltable ?  I love smoothies but I think I kind of relate smoothies to the way I use to make them w/whole yogurt and banana and berries .  I dont mind the taste of veggies but blended sometimes isn't so great texture wise .

My mother makes a good smoothie that is avacado , banana, brown rice protein powder . It looks like green pudding , and tastes like banana pudding with baby cereal in it   But I'm trying to not do grains ( I do do some rice but only once in a while ) , and trying to avoid the sugars in the fruits .. so her recipe although wholesome and tasty is out the window for me .

 I know beet is a good way to add some sweetness without using fruit , but to me a sugar molecule is a sugar molecule is a sugar molecule , so not so sure thats a great idea if you are trying to avoid sugar .

I keep reading and seeing of people here doing sugar free and even watching their fruit intake , and also not doing wheat /gluten .. so thought it would be a good place to ask if anyone has come up wiht any good veggie smoothies that are nice on the taste buds .

 

I don't even try for the sweet, but do use a carrot most of the time with my greens. I also add about a tablespoon of the pulp for the fiber to counteract the natural sweet of the vegetables. I go more for a bloody mary taste, peel and juice a whole lemon or lime, toss in a tomato, sprinkle with some sea salt and cayenne pepper. I don't think of it as a smoothie, just my veggie drink.
Now I do make a good smoothie with coconut milk or almond milk. Freeze some into ice cubes to put in the blender, add some flax, cocoa, coconut oil vanilla, and some kind of sweetener such as stevia. Oh and a scoop of whey powder. It still ends up low on the carb scale, and is good for when I am craving something like ice cream.

I have bad reactions to stevia ( after several attempts )  , it gives me a worse sugar crash than sugar does
