Made these the other night and even got an approval from the man of the house :)
Green beans - washed and ends cut
Preheat oven to 400 and line a baking sheet with parchment paper.
In a bowl toss green beans with olive oil and seasonings. I used a lot of chili powder; I like spice!
Arrange on prepared baking sheet and bake 20-30 minutes, flipping once or twice, until they reach desired crispiness!
