I used Za'atar to flavor the fries. Za'atar is a variable mixture of herbs, often with thyme as a base, used in Middle-Eastern cooking. I've spoken before about buying spices while on vacation. I got this bag of Za'atar at a Lebanese grocery store while visiting friends in Los Angeles.
- Sweet potato
- Ground beef shaped into hamburgers about 1 inch thick
- Za'atar or other herb mix for the potatoes
- Olive oil
- Place an iron grill pan in the oven if you have one (If you don't have an iron grill pan, forego preheating the pan and use a broiling pan with a rack.)
- Turn on the oven and preheat to 400°
- Peeled the sweet potato and cut into french-fry shaped pieces about 1/4 to 1/2 inch thick
- Toss the sweet potato in olive oil to coat.
- Toss the coated potatoes with Za'atar and salt to taste
- Place the potatoes in a single layer on a baking pan
- When the oven is up to heat, cook the potatoes for 10 minutes
- By this time your grill pan should be very hot. Use a barbecue brush to "paint" the grill pan (or rack) with olive oil to prevent sticking.
- Place the hamburger on the oiled grill pan or rack and cook in the oven for 10 minutes.
- Flip the burgers and the potatoes.
- Cook another 10 minutes (30 minutes total for the potatoes, 20 minutes for the burgers)
