Step 1: Prepare the Ingredients
Start by rinsing the canned beans under cold water if you're using them. Drain them well and set aside. Chop the cherry tomatoes, red onion, cucumber, and herbs.
Step 2: Make the Dressing
In a small bowl, whisk together the olive oil, red wine vinegar (or lemon juice), Dijon mustard, minced garlic, salt, and pepper until well combined.
Step 3: Combine Everything
In a large mixing bowl, combine the beans, chopped vegetables, and herbs. Pour the dressing over the salad and toss gently until everything is well coated.
Step 4: Let It Stand
For the best flavor, let the salad sit for at least 30 minutes at room temperature. This allows the beans to soak up the dressing and the flavors to meld beautifully.
Step 5: Serve and Enjoy
Serve the Insalata di Fagioli at room temperature or chilled. This dish is great on its own or served alongside grilled meats or fish.
