In a bowl large enough to hold the carrots, combine the lemon juice, vinegar. a sprinkling of salt and pepper. Whisk in the olive oil.
Peel and grate (or shred) or buy the pre-shredded carrots and add them to the bowl with the dressing.
Toss to combine, taste for salt and pepper and stir in the parsley.
Notes
Other fresh herbs may be used for the parsley or in combination with the parsley. Mint is good in the spring. Thyme also adds a lovely flavor. Have fun experimenting with different herbs! I buy the pre-shredded bags of carrots when I want to make this salad even faster and easier!
