Boil the sweet potato for 5-10 minutes until almost cooked, then drain. Heat a pan, then fry the sweet potato slices in the olive oil until they are brown on both sides. Season them with the spices and salt.

For an appetizer tray, lay out the sweet potatoes on a plate topped with the sliced fresh tomatoes.

For a salad, toss the sweet potatoes in a bowl with the chopped fresh tomatoes.
