Dill is a classic. But also try tarragon, thyme, and rosemary.

In each case, along with the garlic I would add a red chili.

2 lbs whole green beands, trimmed
1 tsp seasoned salt
1 clove garlic, minced
1 slice onion
1/2 lb bacon, cooked & crumbled
1 bunch green onions, chopped
4 oz Roquefort cheese
1/4 cup mayonnaise
2 TBL sour cream

Combine dressing ingredients & shake well. Refrigerate dressing.
Bring a large b\pot of water to a boil. Add green beans, seasoned salt, garlic & onion slice. Reduce heat. Cook until tender. Drain & cool.
Toss beans w/bacon, green onions, Roquefort, 1/4 cup of the dressing, mayonnaise & sour cream. Chill well before serving.~~Food for Thought

GREEN BEANS IN DILL SAUCE (serves 8)
1 1/2 lbs fresh green beans, rinsed, dried, stem ends removed
2 TBL sugar
1/3 cup cider vinegar
2/3 cup olive oil
3/4 cup thinly sliced green onions, tops included
3 TBL chopped parsley
3 TBL minced fresh dill or 1 1/2 tsp dried
1/2 cup coarsely chopped walnuts
Salt & pepper
Dill sprigs for garnish

Place 2 TBL sugar in a heavy medium saucepan. At the same time, bring 2 cups water to a boil in another saucepan. Turn the heat on to high in the pan with the sugar. Watch carefully & when the sugar just begins to melt & bubble, place the beans in the pan, then immediately pour the boiling water over the vegetables. Work w/caution to avoid being scalded. Cover the pan & cook until tender, about 3-5 minutes. Drain & run cool water over the beans to stop the cooking. Drain again thoroughly.
Blend the vinegar & oil into an emulsion by pouring the vinegar into a processor or blender, then adding oil in a slow thin stream. Whirl the emulsion for 1 minute; stir in the green onions, parsley, dill & walnuts. Toss the mixture w/the beans while they are still warm; season w/salt & pepper to taste. Chill for a few hours. Bring the beans to room temperature & garnish w/springs of dill before serving.~~California Treasure
