Make the satays alternating tempeh strips with carrots and onions. Marinate in teriyaki sauce. Grill on low until well -colored and hot through, about 2-3 minutes. Glaze satays occasionally when grilling.
Meanwhile, in a sautee pan on med-high heat, coated lightly with oil sautee the garlic until colored, about 2 minutes. Do not burn. Add the five spice and cream and bring to a boil; allow to reduce until slightly thickened. Add the spinach and toss to coat. Season.
