Bring 3 cups of water to a boil in a 5-quart saucepan. While waiting for the water to boil, trim ends off green beans. Place green beans in a colander or steamer basket. Place colander over the boiling water and cover with a lid, or place steamer basket in steamer and cover. Steam green beans for 2 minutes, or until crisp tender.
Meanwhile, place a non-stick small saute skillet over medium-high heat. Without any oil, add almonds and toss them lightly while sauteing; dry saute until almonds are toasty brown.
Remove almonds from heat and combine with green beans. Toss until well mixed. Season, to taste, with salt, pepper, and lemon juice. Serve warm.
