Bring a medium sized pot of water to a boil and make a large bowl of ice water.
While waiting for the water to boil, cut off both ends of your green beans and also cut in half.
Place into boiling water for 1-3 minutes.
After the allotted time, place greenbeans directly into ice water to stop the cooking process.
Slice grape tomatoes in half and dice red onion.
Pat dry the green beans and place in a dish. Add tomatoes, onions (if you want them), and almonds. Then squeeze the juice of your one lemon, add the extra virgin olive oil, salt, and pepper. Mix will.
You can eat it right away but for best flavor, place in fridge for 30 minutes.
