I got into juicing thanks to this thread from MikeCF. It's great. I think this is the healthiest I've been eating my entire life.
Anyway, I have a little tip that I do myself that might be of interest to others. I have a masticating juicer, so I'm not sure if the other kind would produce the same type of by-product. This is for when you juice veggies. You basically get all these fibers and solid pieces of the veggies left over that has all the fibers and probably still a reasonable amount of nutrients as well.
Most of that, I throw away because it is just too much since I juice every day. I could get into composting and growing your own organic stuff later if there's interest on that. But this is just for these solid left over stuff that are basically shredded fiber.
What I do is this: I buy a large pack of ground beef (usually choose the one with the highest fat content which is generally cheaper and/or on sale, and since I'm lifting now as well, I think it's supposed to help me gain muscles?). Then I take the ground beef and mix it up with the veggies fiber, and add in some soy sauce for flavoring. I make these into meat balls and put them into separate zip-lock bags and freeze them in the freezer.
Later on, I can just take a bag of meatballs out and easily boil it in some water to either just eat the meatballs, or also have it like a meatball soup
Nice and simple, and helps add fiber to your diet and maybe will help with the digestion of the meatballs.
Edit: Word of advice: make your juice, drink it, clean up and put away your juicer before you get the meat and make the meatballs to help avoid cross contamination.
