French Style Bean Salad

David really likes green beans so I try to make them in various forms - steamed, in recipes, etc. This is a great cool side item for the hot summer months.

1 can French style green beans, drained
2 tsp lemon juice
1/8 tsp salt
2 and 1/3 Tbsp mayonnaise
1 and 1/3 Tbsp chopped onion

Mix lemon juice, salt, mayonnaise and onion. Pour over beans; toss well. Refrigerate and serve.
