Cut or tear the mushrooms by hand into long stripes.
Season them with the salt, black pepper, fresh thyme, garlic and a drizzle of oil.
Cook them on a hot griddle pan for 5-6 minutes on each side.
Meanwhile you can start with the sweet chili sauce.
Add the ingredients for the sauce in a saucepan or any deep pan that you have, except the starch.
Let it simmer for 4-5 minutes and now add the cornstarch.
Cook for another minute until it becomes a bit richer in color and a lot thicker.
Take it off the heat and let it cool down - this will thicken it a bit more.
Serve and enjoy!
