Korean BBQ style served with kimchi, sesame oil and perilla leaves and lettuce is a great way to enjoy beef with plenty of flavours and vegetables.
Another way not mentioned so far is Japanese Sukiyaki style. Heat up a pot with green onions, and sweet onions. Add in sliced beef (preferably rib eye or short rib) with a broth comprised of Sukiyaki sauce (can be made with a mixture of mirin, soy sauce, cooking wine/sake, sugar, dashi). Then add in tofu, cabbage and mushrooms. Lastly add in Udon noodles to enjoy with the leftover broth. When you get a good cut of beef, sukiyaki is very enjoyable as you get to enjoy beef with vegetables.
