Grilled Beef Rolls with Enoki Mushrooms

I first saw Beef Rolls with Enoki Mushrooms on Sakae Sushi's menu. Decided to experiment and come up with my own version. But for some reasons, my version look similar to vegetable rolls as shown below. 奇怪了。

The beef rolls that I saw on Sakae's menu, it looks like the sliced beef are cooked with boiling water. But I am grilling mine as I like the slightly charred taste.

Ingredients
10 pieces of thinly sliced beef
1 packet of enoki mushrooms
Carrot (cut into shreds, about 3" long) - 10 pieces
Spring onions (cut into about 3" long) - 10 pieces
Teriyaki Sauce

Preparation
Cook enoki mushrooms in boiling water for 10 seconds.
Drain, divide the mushrooms into 10 small bundles and set aside.
Cook the carrots in boiling water for a minute.
Remove from heat and drain.
Wrap a piece of carrot and spring onion together with a small bundle of enoki mushrooms using a piece of sliced beef.
Repeat procedure until all the beef, carrots and spring onions are used up.
Grill the beef rolls in an oiled pan with the flaps facing down.
Remove from heat when the beef rolls are cooked.
Add 5 tablespoons of teriyaki sauce into the pan.
Bring to a boil and pour the sauce over the beef rolls.
