Vegetables (onion, green bell peppers, carrots, garlic, etc.)
as much as you'd like
Basil butter (Recipe ID: 1060447)
Salt and pepper
Garlic soy sauce
Slice the beef against the grain (as if cutting through the tendon) then pound it using the handle of your knife to soften. Season with salt and pepper.
Marinate the beef in olive oil for at least 30 minutes along with the chopped vegetables. I've heard this makes the resulting steak absorb the flavor of the vegetables, hence making it tender.
Stir-fry the vegetables before cooking the meat. Using the same frying pan, cook the meat to your preference. Dish it up, and top with basil butter.
Also serve with garlic soy sauce or your preferred steak sauce.

Story Behind this Recipe
When I was a student, my friend's mother told me that cooking the meat this way would make it tender. I'm not sure if this is true or false, but nevertheless, that's how I've cooked beef since then.
Serving this steak with fancy sauce sounds great too, but it's also amazing with "Super Versatile Garlic Soy Sauce" (Recipe ID: 1006640). If you don't have "Basil Butter" (Recipe ID: 1060447), you can also use regular butter.
