Add the dehydrated soy chunks to a large bowl and cover them with boiling hot water, then drain them after 10 minutes. Allow the soy chunks to cool until they are not too hot to touch, then squeeze the excess water out of them. Add them back to the large bowl and season them with turmeric, paprika, garlic powder, onion powder, ground cloves, dried thyme and salt.
Add 3 tablespoons (45 ml) of the oil to a large nonstick skillet over medium-high heat. Brown the soy chunks in the hot oil, stirring them around occasionally for 5 minutes, then remove the soy chunks from the skillet and set them aside.
Add the remaining 1 tablespoon (15 ml) of oil to the same nonstick skillet over medium-heat heat. Sauté the onion, garlic cloves, Scotch bonnet pepper and bell peppers for 2 minutes, or until the onions are translucent.
Mix in the soy chunks. Use the hot water to dissolve the bouillon cube, then pour the liquid into the skillet. Mix in the tomato paste, ketchup, browning sauce, soy sauce, white vinegar and fresh thyme.
Cover the skillet, lower the heat to medium and let the soy chunks cook for 10 minutes. Uncover the pot, mix in the cumin and coriander, add a little more hot water if you prefer more gravy and cook for 5 more minutes.
Enjoy these chunks in island gravy with white rice, rice and peas or with roti.
