Cut the root end off your bok choy, separate each stalk from the base, and rinse each leaf under cold running water to remove any dirt or debris.
Cut bok choy into 1/4 inch slices. Prepare all the veggies. Set aside
Heat oil in a large saucepan over medium-high heat, add onion, and cook until soft, about 2 minutes.
Stir in garlic, green onion, bell pepper, and thyme, and cook until fragrant, about 1 minute.
Add tomatoes, carrot, vegan bouillon, bok choy, and Scotch pepper, and stir.
Bok choy will wilt and release its own liquid. Cover the saucepan and reduce heat. Cook until bok choy is tender, about 10 minutes. Serve immediately
