これ、焼けたよ！どうぞどうぞ。 — This one's done! Here you go, help yourself! (Cultural · Dining, Casual — to friend, JLPT N4)

Gesture & etiquette

Use the separate serving chopsticks (not your eating ones) to lift pieces off the grill; place them gently on the other person's plate or a serving dish; smile and gesture toward their plate with an open hand to invite them.

At yakiniku, the attentive guest monitors the grill and serves others before themselves — this is a strong sign of social consideration (気遣い). Always use the dedicated serving chopsticks (取り箸/サービス箸), never your own eating chopsticks, when placing grilled pieces on others' plates.
