In a small jar, add lemon juice, olive oil, minced garlic, Dijon mustard, and a pinch of salt and black pepper. Shake vigorously for about 30 seconds until well combined. Set aside.

In a large mixing bowl, combine drained white beans, diced tomatoes, diced cucumber, chopped red onion, parsley, and mint.

Gently toss the salad ingredients to mix well, ensuring even distribution of beans and vegetables.

Drizzle three-quarters of the dressing over the salad mixture and toss for about 1-2 minutes until well coated.

Transfer to a serving bowl. Taste and adjust with more salt, pepper, or dressing if needed. Serve immediately.
