Kidney Bean, Tomato & Red Onion Salad

I saw this on Nigella Bites last night and made it for lunch today. We had it with crusty olive bread, but it would be nice as part of a buffet or picnic or as a potluck dish. It's very quick and easy to make, healthy and quite tasty. I used one can of beans, vine-ripened tomatoes, and everything else as listed in the recipe.

• Ready In: 7 mins
• Serves: 6

Ingredients

• 1⁄2 red onion, finely chopped
• 2  tablespoons red wine vinegar
• 2  cups cherry tomatoes
• 1  teaspoon fine sea salt (or more)
• 3 (14 ounce) cans red kidney beans, rinsed and drained
• 2  tablespoons extra virgin olive oil

Directions

1. In a small bowl, combine onions and vinegar. Set aside to macerate while preparing rest of salad, or up to three hours.
2. Halve cherry tomatoes and place in a serving bowl. Sprinkle with 1 teaspoon salt. Add kidney beans, onion mixture and olive oil. Toss gently to mix, adjust salt to taste, and serve.
