I enjoy tempeh plain, I enjoy marinating it myself, and sometimes I buy pre-marinated tempeh. If you're going to marinate it, begin by tossing plain cubed tempeh in your savory marinade of choice. It doesn't have to be submerged, just toss to coat in a lidded container and turn it upside down every 5 minutes or so. Marinate for at least 15 minutes. (See notes for my favorite tempeh marinades)
Preheat the oven to 400° F and line a baking sheet with parchment paper.
Toss the cubed potatoes and diced veggies in a tiny bit of olive oil and a pinch of salt, pepper, and any additional dried herbs that sound good to you.
Spread the potatoes and veggies out in a single layer on the baking sheet and place in the oven.
Make Tahini Sauce
While the potatoes are roasting, make the herb sauce by blending all ingredients in a small blender cup, or in a small jar with an immersion blender. Add water to reach desired consistency. Divide into 4 equal servings, or use about 2 Tbsp for a single serving.
Tempeh & Veggies
After the potatoes have been in for about 15 minutes, add the tempeh to a non-stick skillet over medium low heat, along with a splash of olive oil.
Pan fry the tempeh for 5 minutes tossing occasionally, until beginning to turn brown.
Add your hash veggie of choice into the pan with the tempeh, and pan fry until cooked to your liking.
Toss the veggie and tempeh mixture with the potatoes, drizzle with the sauce, and enjoy!
