Preheat oven to 375 degrees F

Toss green beans with olive oil, salt and pepper. Arrange in a single layer on a baking sheet and cover with aluminum foil. Bake until tender, about 15-20 minutes.

While the green beans are baking, sauté garlic in a non-stick or slightly greased skillet on low heat until soft and slightly brown, about 3 minutes. Set aside. In the same skillet turn the heat up to medium and toast pine nuts until slightly brown, about 2 minutes. Set aside.

When green beans are done toss with lemon juice, and top with garlic, pinenuts and optional cheese. Serve immediately.
