I don’t know, there’s a lot of boring old dishes where boiling the water basically all wait time.
Like if I’m making real boring pasta:
1. Xm to boil 2. 10m to cook pasta 3. 3m to microwave meatballs 4. 1m30s to microwave sauce
The meatballs and the sauce both fit within the pasta cook time, so boil time is all wait.
