Preheat oven to 450F, then add 1/4 Cup Pecans to your food processor.

Grind the pecans in the food processor until they are chopped nicely. Some pieces should be large, some small.

In a large mixing bowl, mix together green beans, pecans, olive oil, parmesan cheese, the zest of 1 lemon, minced garlic, and red pepper flakes.

Spread out the green beans on a foiled baking sheet.

Roast the green beans in the oven for 20-25 minutes.

Let cool for 4-5 minutes, then serve!
