sulcata tortoise food source

I want to know what are your guys go to vegetables and other stuff to feed your tortoise what’s the best options for them? And where do you guys get it from.

Hi, I have 6 rather large Sulcata's that range from about 40 pounds up to 100 pounds. Needless to say, they eat a lot and I need supplemental food to fill in when we are unable to get weeds, greens, etc. We have been ordering from Mazuri for the past 5 years but their prices have gone up up...
