Marinated Chickpeas with Bell Peppers and Cucumbers

0 In a large mixing bowl, whisk together olive oil, vinegar, mustard, honey, Italian seasoning, paprika, salt, and pepper.
1 Stir in beans, bell peppers, cucumbers, and red onions until evenly combined.
2 Refrigerate for at least an hour and up to 3 days (the flavors will continue to develop the longer the chickpeas marinate). 
3 Stir in basil right before serving. Serve chilled or room temperature.
