Peel carrots and slice them into thick rounds. Simmer in a pot of salted water until just tender.

While carrots cook, whisk together olive oil, vinegar, mint, garlic, salt and pepper.

When carrots are fork tender, drain them.

Toss warm carrots together with vinaigrette and let them sit until carrots are cool.

Place carrots in refrigerator and let them marinate for at least 1 hour before serving. They can be kept in the refrigerator for up to 5 days.
