Preheat oven to 350 F. Place the almonds on a baking sheet in a single layer.
Toast in the oven for about 10 minutes, stirring every 2 minutes or so until the almonds are toasted and fragrant.
Remove from the oven and pour almonds onto a cold plate until the Sriracha sauce is done.
For the Sriracha and brown sugar sauce: Put the brown sugar, Sriracha and soy sauce into a small saucepan and bring to a gentle simmer, stirring and heating just until the brown sugar is dissolved.
Immediately pour it over the almonds and toss to coat the almonds.
