Sauté pancetta and garlic over medium heat for about a few minutes, or until desired level of crispiness is achieved. Remove pancetta and garlic and set aside in a bowl.
Add green beans, onion powder, salt, and pepper to pan. If you want a little more oil, add a tsp of olive oil. Cook for about 10 minutes, or until the beans are hot all the way through.
While the beans are cooking, toast the almond slivers in a separate pan over medium heat. These will burn quickly, so keep an eye on them and toss them often.
When green beans are done, add the pancetta and garlic back to the pan and warm. Toss in the slivered almonds and mix to combine.
