This exact amount yeilded about 16 oz of juice...which was really two servings...so BONUS! When "juicing" greens, I've found that it's easier to ball them up into a tight wad (technical term here...don't judge)...and wedge it between two harder slices of something. In this case, I wedged it between two pieces of sweet potato. It seems to have worked well. For this amount of spinach, I got about 1 tsp of juice. Maybe a little more. Not even sure if I get the healthy benefits from that - but it does turn the juice a nice color of brownish green - which grosses out my kids, so, there's that.
Tomato Vegetable
1 Large Beefsteak Tomato
1 cup fresh spinach leaves
1 small red bell pepper
3 mint leaves
1/2 large sweet potato
2 med. stalks celery
Again, I do not peel, slice, or remove the seeds from any of these vegetables. I'm far too efficient (read lazy) for that. My juicer has the capacity to do so - one of it's biggest selling points. :) I use a Breville Juice Fountain Multi-speed 900 W juicer, and I do love it so! If you'd like one for your very own, you can check them out here on Amazon.
