Start by prepping ingredients. Slice garlic cloves and juice 1 lemon.
Heat the olive oil over medium heat in a medium-sized saucepan.
Next, lightly season the tempeh with garlic salt and pepper on each side.
Cook the tempeh until golden on each side. Set tempeh aside.
Cook the sliced garlic over low-medium heat in the same pan until fragrant (about 1-2 minutes). Be aware that garlic burns easily and can give the sauce a bitter taste.
Pour in the white wine and let it simmer for a few minutes. Then add the vegetable broth, lemon juice, capers, and vegan butter. Mix.
Add the Wondra Flour®, mix the sauce, and let it simmer until it begins to thicken. More may need to be added to thicken to your liking.
Test-taste the sauce. Based on your preference, more broth or lemon juice can be added to your liking to balance the flavor.
Add the spinach until it wilts into the sauce.
Add the tempeh back into the pan and coat with sauce.
Serve tempeh and sauce mixture over your choice of pasta, rice, or more spinach. Enjoy!
*You can exclude the vegan butter and white wine if preferred. It tastes great on its own as well!
*If you do not have Wondra Flour®, you can use regular flour as a replacement.
