I got on trying to eating more healthy and as a part of that, I take a few tomatoes, cucumber and garlic and blend that into a sort of a drink. It's far more convenient and quick to smash a bunch of veggies into a blender and mix the crap out of them, rather than slicing and hacking. It also scales better - making a mixaroo of 3 or of 5 tomatoes takes the same amount of time, whereas slicing time is proportional. So I'm aiming at eliminating any obstacles along the way to wiser food choices.
I'd like to make it less liquidish, aiming for a thicker texture. I've tried adding broccoli, cauliflower, nuts and seeds. I tried adding oat flower and soy protein powder. It gave an improvement but to be acceptably substantial, I need to push in quite a lot, which kind of defeats its purpose.
Is there something very calorie thin but structurally dense that I could smash into my drink? Extra bonus if it's rich on fiber.
