The
homemade brioche burger buns I had in the freezer, so I took them out in the morning. I cut the buns in half and toasted them for a few minutes on the inside and 30 seconds on the outside: They should only be warmed on the outside, whereas the inside is toasted crispy, partly so the bread does not soak up all the dressing. You can certainly use store-bought buns, such as spice buns instead.
