Cook the Brussels sprouts for about 8 minutes (depending on how big they are, you can test one to see if it's smashable (soft enough) without becoming pulp (too soft).
Carefully 'smash' the sprouts with the bottom of a glass.
When the tomatoes are ready, take the rack out of the oven and the tomatoes off the baking sheet.
Turn the oven heat up to 180℃.
Put the smashed sprouts on the baking sheet.
Mix the baharat with some olive oil. Use a silicone brush to put baharat oil on each smashed sprout. Grate some Parmesan on top.
Put the sprouts in the oven for 8-10 minutes until a bit crunchy.
