Wash all your vegetables thoroughly under cold water.
Dice the tomatoes into bite-sized pieces.
In a large mixing bowl, combine diced tomatoes, sliced cucumbers, chopped red onions, and bell peppers.
Drizzle olive oil and freshly squeezed lemon juice over the veggies.
Sprinkle crumbled feta cheese on top.
Chop up your fresh herbs finely and toss them into the mixture.
Cover the bowl with plastic wrap or a lid and let it chill in the fridge for about 15-20 minutes.
Remove from the fridge, give it one last gentle stir, then serve on a colorful plate or in individual bowls.
