Traditionally made with chicken, this chipotle-forward Mexican stew is delicious made with roasted oyster mushrooms. Serve in tacos or on tostadas with lime, sliced avocado, chopped cilantro & white onion.
Preheat oven to 220°C/425°F. Add the mushrooms to a large bowl and drizzle with 2 tbsp of the oil. Season generously with salt and stir to combine. Spread over a parchment-lined baking tray and roast until reduced in size, lightly golden and crisp, 20-30 minutes, stirring halfway through.
Add the remaining 2 tbsp of neutral oil to a large saucepan and set over medium heat. Once shimmering, add the onion and season with a generous pinch of salt. Cook, stirring occasionally, until the onions are softened and beignning to brown around the edges - about 7-10 mintues.
Add the garlic and tomato paste. Cook, stirring constantly, until the tomato paste darkens and begins to stick to the bottom of the pan - about 2-3 minutes. Stir in the cumin and cinnamon and cook just until very fragrant - only about 30 seconds longer.
Add the tomatoes and stir to combine. Cook, stirring occasionally, until the tomatoes have broken down significantly - about 5 minutes.
Stir in the chipotle chiles and the vegetable stock. Bring to a simmer. Stir in the roasted mushrooms. Allow to simmer for 10-15 minutes, stirring occasionally, until the tinga is lightly thickened and the flavours are homogenous. Remove from the heat and stir in the lime juice. Serve immediately.
