If you have high ability, vegetarian food can also be delicious. I can tell you that the vegetarian diet in Foguangshan Temple is in place. I have many friends. They all went to the temple for dinner. I took many people to temples and had meals at Foguangshan Temple, and they were all very happy.
I am also a vegetarian at home. But because of work and other reasons, I am not a vegetarian. Vegetarian at home, casual outside. Some friends came home, and I made vegetarian pies for them. They were all satisfied.
If your vegetarian ability is not satisfactory, it is no problem to cook some meat dishes when entertaining friends. Everything is fate. Buddhism says to make good relations. If you want to get married well, you need many conveniences. Don't stick to the form of learning Buddha.
