Sea salt gives these roasted nuts a clean, salty flavor.
Preheat oven to 350 degrees. Spread the almonds in a single layer on a rimmed baking sheet, and toast in oven until golden, about 15 minutes. Let the nuts cool completely, then transfer to a small bowl. Add oil and salt, and toss until almonds are well coated.
Store almond mixture in an airtight container at room temperature until ready to serve, up to 2 days.
