...These came out rather good on the grill actually!

1 bag of multi colored carrots (or regular), peeled, chopped in half with the tops removed
small handful of fresh rosemary
6 - 7 whole garlic cloves, peeled
2 tablespoons olive oil
salt and pepper
dash of italian seasoning

2 foil sheets, to put them in separate packets...coat the veggies all over with the oil and seasonings, then packet them up...

And let roast in the grill at 350F for about 35 minutes!
