Spread almonds in an even layer onto the prepared baking sheet. Place into oven and bake until toasted, about 10 minutes; set aside.
In a medium saucepan, combine butter, sugar vanilla and salt over medium heat. Cook, whisking constantly, until butter has melted and mixture is almond brown in color, about 10-15 minutes.
Immediately spread the hot toffee mixture evenly over the almonds. Sprinkle with chocolate chips. After 1-2 minutes, spread the chocolate chips in an even layer until smooth. Sprinkle with pecans.
Let cool completely, about 2 hours. Break into pieces.
