I love pumpkin seeds. Have you tried the pumpkin seeds butter with greens?
I soaked and dried on our radiator some pumpkin seeds. I happened to have delicious sprouts - I love combining those too!
My juicer is masticating (19 years old now!) - I put the pumpkin seeds through first, then the greens, and mixed it together.
My dog Pepper loves nuts and seeds. In fact, one time I left my Brazil nuts and walnuts to dry on a windowsill - Pepper ate them all! when I wasn't home :)
Earlier this morning, I made the vegetable juice from butternut squash, cucumber, parsnip and Brussel sprouts - I used that pulp at the end, after processing the kabocha and butternut squash seeds I saved for Pepper.
Isn't amazing how much commercial "dog food" is out there, when all our animals need is real fresh food. Pepper loves raw meat, veggies, fruit, etc. She always licks her plate clean :)
