If you buy a high-powered blender, and I mean like a vita mix, you can break down your veges to a blended drink. The most tolerable is mixture of apple (peel), lettuce, spinach, carrot and maybe quarter stick celery but.... most all blenders unless you get like a Vitamix or similar will not break down greens enough to be smooth. The great thing about doing it this way is the food is broken down to its cellular level and is highly absorbable for those like us who need quick easy absorption. No all veges are going to agree with you. Some people can tolerate citrus like oranges but I can’t tolerate any citric acid or it burns. Therefore I Switch out certain items from the recipes. Banana in fruit smoothie is good with like an almond milk and maybe handful of strawberries. Check out you tube videos on the Vitamix to see what it does. Other blenders seem to leave green pieces which don’t make it taste great and weird texture. I don’t think it’s good to stay away from vegetables but choose those that are softer and not so fibrous. I couldn’t do without my rice steamer that has an added basket on top to steam vegetables without oils or fats. I steam mostly carrots thinly sliced with thin sliced zucchini or similar more easily digested nutritious ones in the top basket while the rice cooks. You can steam quartered white or sweet potato as well. I have good luck with those and sweet potato is full of good nutrients. Also you can steam some fruits to soften as well.
