SIMPLE ROASTED CARROTS & ONIONS

Steps:

Cut carrots into 2 - 3" pieces, and if the carrots are really fat, cut them lengthwise into halvves or quarters. (You can adjust the quanitities of everything -- it's just that the program here wants specifics.).

• Roast for 15 minutes, turn and roast for 15 - 30 minutes more. At this point, they should be cooked, but they can go longer if they're not done. they should be crisp/tender (if they go longer, they get soft, which I'm starting to like, too) and have browned spots on them.
