Cut the bell pepper, onion, cucumber, and tomatoes.
Add all into a bowl with the crumbled feta cheese and olives.
Properly mix the ingredients and the oregano and salt.
In another small bowl, mix together the minced garlic clove, vinegar, and olive oil to be used as the salad dressing.
Serve in a platter and enjoy!
Notes:
Because you are not cooking anything for this dish, you may be worried about garlic on your breath. In that case, you can remove it from the recipe. But note that onion is vital if you want the salad to have its delicious taste.
If capers are your thing, feel free to add them to the salad. Capers are really low carb.
