Preheat oven to 400°F (200°C). Cook the bacon in a pan. Once cooked, pour the bacon fat over the almonds in a bowl and set the bacon strips aside. Toss the almonds to coat them in the fat, then bake for 5 to 7 minutes. While the almonds are baking, mix sugar, salt, and pepper in a small bowl. Remove the almonds from the oven and pat off any excess fat with a paper towel (or shake them in a brown bag). Crumble the cooked bacon strips and add the bacon bits and the sugar mixture to the top of the almonds, then toss to combine.
