Mix ground flax and water and set aside for 2-3 minutes to gel.
1 tbsp ground flaxseed, 3 tbsp water
Crumble tofu in a nut milk bag or cheesecloth to remove excess water.
1 lb extra firm tofu
Add onions and carrots to a microwave-safe bowl with a splash of water. Cover and microwave 1-2 minutes until just tender. Or cook in a fry pan with a little bit of oil.
In a large bowl, combine vegan ground beef, tofu, flax, onions, carrots, breadcrumbs, garlic, parsley, thyme, oregano, black pepper, and 2 tbsp of sauce. Knead together with your hands until well combined and slightly sticky - but it shouldn't stick to your hands too much. Cover and rest in the fridge for at least 20 minutes.
1 lb vegan ground beef, ½ cup breadcrumbs or torn up stale bread1, 2 cloves garlic, 1 tbsp fresh parsley, 1 tsp dried thyme, 1 tsp dried oregano, ¼ tsp ground black pepper
Shape into patties. Throw each patty back and forth between your hands a few times to remove air bubbles.
Heat a nonstick pan over medium high heat and grease with a little bit of oil. Place patties on the pan with some space between each (you probably have to cook in 2-3 batches) and press down on the middle of the patties to promote even cooking.
Cook for about 4 minutes until browned on the bottom, then flip. Add 1/4 cup water/vegetable broth/red wine, cover, and reduce heat to medium low. Steam for 5-6 minutes until cooked through. Uncover and increase heat to medium high. Continue cooking until all the liquid evaporates. Transfer hambagu to a plate and repeat with remaining patties.
To the empty (unwashed) pan over medium heat, add sauce and 1/4 cup water/vegetable broth/red wine. Simmer and stir the sauce for a minute or two until thickened. Pour the sauce over the hambagu or serve on the side.
Notes
1) Breadcrumbs: I've also used chickpea flour instead of breadcrumbs. Start with about half the amount and add more as needed.2) Chuno Sauce: If you can't find Chuno sauce, you can use vegan Worcestershire sauce* and add a bit of sugar.
