Use milk to get meat eaters to take to Masada, see quotes below to support the premise.
The milk is nothing, but it is cow’s blood transformed. Just like mother’s milk. The mother’s milk, wherefrom it comes? It comes from the blood, but transformed in such a way that it becomes nutritious to the child, tasteful to the child. Similarly, cow’s milk also, a most nutritious and valuable food.
Bhagavad-gita 7.3 — Montreal, June 3, 1968
Yes, you do not know. You do not know how to utilize the animal. Ignorance. The milk is also produced out of the blood.
So it is intelligence. You are drinking the blood in a different way, produced by nature with more vitamin values and more taste and more gentleman. Why should you kill one cow and try to drink the blood? The blood is there already, but in a different form, without any violence.
Srimad-Bhagavatam 6.1.17 — Denver, June 30, 1975
Another business is to protect the cows, and to give them food nicely so the cows will give enough milk. And from milk, you know, so many nice preparations, all full of vitamins. So why they should be killed? You are killing; the blood is not utilized, you are taking the flesh. But flesh is transformation of the blood. And milk is also transformation of the blood. So if you take, just like channa, it is as good as flesh. By taste, by benefit — as good as. So why if you can take the flesh and blood in a human way-blood is transformed into milk, and from milk there are so many good preparations-ghee, yoghurt, burfi, channa, so many preparations are available. This panir, channa, and let the animal live peacefully. Why are you cutting his throat? You require some benefit from the animal. Take this benefit. Why should you kill?

“They cannot give up that small piece of meat. What is the difficulty? The same thing can be made by milk, milk product, channa. What do you call curd? Cheese. You prepare cheese and fry it. You’ll get the same taste.”
Lecture, London, 12 July ’73 / Conversation, Melbourne, 2 July ‘74
“It is a very good idea for people to come to our vegetarian restaurant and take so many nice things, especially the panir, fried cheese, and sandesh, kachori, rasagulla, samosa and in this way they will forget their meat-eating. If you make a soup of fried panir with asafoetida and ginger, this will replace lobster soup nonsense.”
