Cut the bread into one inch pieces. Sprinkle with 1⁄2 cup water and let it rest for two minutes. Squeeze the bread with care till is dry. Tear it into one inch pieces and let it sit on paper towels for approx. 20 minutes.
Boil water into a big saucepan. Add the green and yellow beans and cook until it has a tender consistency but still crunchy, approx. three to five minutes. Drain and let it cool.
Arrange the onions, the tomatoes, the green and yellow beans (cooled) and the bread in a big serving dish. Shred the basil into 1⁄2-inch portions and toss carefully into the dish alongside with the oregano.
In a small dish, whisk together garlic, the vinegar and oil. Spice it up with Mediterranean Sea salt and pepper. Toss the salad with the vinaigrette and let it sit for approx. 20 minutes. Arrange the crumbled feta on top to serve and enjoy!
