FYI: all of the following quick recipes use fresh green beans. I'm sure frozen would work as well, but I wouldn't use canned.
Spread a single-layer of fresh green beans (ends snapped) on a cookie sheet. Drizzle with olive oil, sprinkle with salt. Bake for 10 minutes at 350... or about that. It depends on how crispy or tender you like your beans.
Beans & Cranberries
Steam or boil fresh green beans and 1 tsp orange peel. When done to your liking, place beans in serving bowl. Stir in 1/2 cup cranberries and 2 Tbsp honey. Optional: top with bacon bits or bacon crumbles.
Green Beans w/ Garlic Vinaigrette
Cook 2 1/2 lbs beans to your preference (oven, steam, boil, doesn't matter). Combine & whisk in large bowl: 1/2 tsp lemon zest, 1 Tbsp lemon juice, 2 tsp evoo, 1 tsp dijon mustard, 1/2 tsp salt, 1/4 tsp black pepper, 2 minced garlic cloves. Add beans, toss to coat. Top with toasted almonds.
