Rehydrate TVP in hot water for 10 minutes. Add flax meal to water and let it thicken at room temperature.
Chop vegetables and aromatics finely: onions, shitake mushrooms, carrots, TVP.
Saute cumin and fennel seeds in oil for 1-2 minutes. Add onions and saute until translucent.
Add chopped green chili, minced garlic and ginger paste. Saute for a few minutes.
Add chopped shitake mushrooms, dry spices and saute until spices are cooked.
Add in tomato paste, carrots, TVP, light soy sauce, worchesterchire sauce, salt and black pepper. Saute until vegetables are cooked and well combined.
Finally add in frozen peas and give it a good mix. Let cool.
To the mixture, add oat flour, ground walnuts and flaxmeal. Mix until well combined.
Preheat your oven to 400°F (200°C).
Roll out the puff pastry on a lightly floured surface. Lay it out flat, ensuring it’s big enough to wrap around your filling.
Spoon the cooled keema filling into the center of the pastry, shaping it into a log shape (similar to a sausage roll). Leave about 2 inches of space on all sides for folding.
Carefully fold the sides of the pastry over the filling, then roll it up tightly, pinching the edges to seal the seams. If you have extra pastry, you can create a decorative top or design. Place the Wellington seam-side down on a baking sheet lined with parchment paper. Score in a criss cross fashion.
Brush the entire surface of the wellington with the vegan butter.
Bake for 20-25 minutes or until the pastry is golden brown and crispy. I like to grill it for 2 minutes to get the top golden brown. Be careful not to burn.
While that's baking make your sauce: saute some minced garlic in oil. Add spices and saute them until cooked.
Add water, veg stock cube, and whisk gently until there are no clumps while on stove. Add coconut milk, light soy sauce and corn starch slurry. Bring to a boil and let it thicken.
Let the Keema Wellington rest for about 10 minutes before slicing. This helps the filling set and makes for cleaner cuts.
Drizzle the gravy over the wellington before serving. Enjoy!
