Add chickpeas, cucumber, tomatoes, red onion and parsley to a bowl.
Measure out olive oil into a liquid measuring cup, pour in lemon juice, garlic, Italian seasoning and season with salt and pepper to taste.
Pour dressing over mixture in bowl. Toss to evenly coat, season with more salt to taste if needed. Salad will taste good for a few days but texturally it's best eaten within a few hours.
Notes
Garden cucumbers can be substituted just peel first.
Grape tomatoes will work in place of Roma tomatoes (use 1.5 cups).
Red wine or white wine vinegar can be substituted for lemon juice.
