2 large orange-fleshed sweet potatoes (sometimes called yams in U.S. grocery stores), cut in 1 inch cubes
2 small red onions, cut into pieces just larger than 1 inch
2 T olive oil (or slightly more, enough to coat all the veggies with oil)
1 T seasoning for Spicy Sweet Potato Fries
1/3 cup Feta cheese

2 large orange-fleshed sweet potatoes (sometimes called yams in U.S. grocery stores), cut in 1 inch cubes 2 small red onions, cut into pieces just larger than 1 inch 2 T olive oil (or slightly more, enough to coat all the veggies with oil) 1 T seasoning for Spicy Sweet Potato Fries 1/3 cup Feta cheese

Preheat oven to 450F/230C.

Peel sweet potatoes and cut into cubes about 1 inch square. Peel red onions and cut into pieces slightly over 1 inch square. Put sweet potatoes and onions into a bowl and toss with 2 tablespoons olive oil (or slightly more if you need it to get all the veggies coated with olive oil.) Sprinkle 1 tablespoon seasoning for Spicy Sweet Potato Fries over the veggie mixture and toss until all the vegetables are coated with the seasoning mix.

Spray a large baking sheet with non-stick spray or mist with olive oil. Spread the vegetables out on the baking sheet (use two baking sheets if they're even slightly crowded.) Roast about 15 minutes, then flip them over with a turner.

Roast 15 minutes more, then flip them over again. Roast 10-20 minutes more, or until the sweet potatoes and onions are both nicely browned and sweet potatoes are soft. (They don't get very crisp, but there should be some browning on the edges.) Total roasting time will be 40-50 minutes, depending on the size of the sweet potatoes, your pan, and the oven.
