Heat a large pot over medium-high heat and add oil. Saute onion, carrots, and garlic, sealing them one at a time (sealing is important for developing a good flavor) (about 15 minutes total).
During this process, prepare tempeh. First, dab the oil on all sides of all the tempeh cubes, then heat a pan over medium-high heat and add the tempeh. Seal on all sides. When finished, turn off heat, let sit 3 minutes, and then splash the tamari evenly on all pieces all around the pan. Set aside.
After vegetables are sealed, add the thyme and flour to the vegetables (add the flour slowly so it does not clump) and cook 2 more minutes. Add the prepared tempeh, peas, wine, water, bay leaf, salt, and black pepper and simmer for 10+ minutes, or until it has thickened to a sauce consistency.
Before serving, remove bay leaf and stir in tamari. Serve over brown rice. Garnish each plate with green onions.
Serving Ideas:
Serve over brown rice.
Use a decent red wine (one you would drink) for the best flavor.
