Step 1

In a medium bowl, whisk together the lemon juice, garlic, salt, pepper, and sugar until well blended.

Step 2

In a large bowl, combine the bell peppers, cucumber, red onion, chives, and mint.

Step 3

Pour the dressing over the vegetables and toss with tongs to combine.  Serve immediately, or cover and refrigerate for up to 30 minutes then serve.  You'll want the cucumbers and bell peppers to still be crunchy.
