How to cope up with this idiotic woman please advise?

I have one sis in law who is the eldest about 55years having one son in degree who has settled permanently in our house. I am the youngest daughter in law who got married just one year back. I am a vegeterian. But they are all nv. Weekly three or 4 days nv. & i still eat food from my moms place. All of them dump work loads on me a lot as i am the youngest and they run away to work early. So i have to feed their children, pack food and look after sick mother in law cook food for lunch for them (16 members ) and then leave for office. At this rate, yesterday my sis in law says me go and clean the mutton. I dont touch only that nv. But serve all sorts of nv for my hubby and others. But raw nv i hate to see also. Yesterday she ordered me in front of a relative. But i directly for the first time boldly told i am sorry i cannot do that work. So she has complained to everybody at home. I am scared to go home from office as i dont know what drama will she play today in front of others.

You are on the right path. Stand up for yourself. Whatever you do, don't back down now. I'm not a vegetarian, but that's not the point. The point is they are not showing you any respect. It may be difficult for a few days, but in the long run you will be much better off.
