Preheat the oven to 425 degrees F. Line 2 sheet pans with silicone baking mats.
For the bacon: Combine the orange juice, vinegar, soy sauce, brown sugar, star anise and allspice in a small saucepan over medium-high heat and reduce by half. In the meantime,
spread the bacon strips onto 1 prepared sheet pan in a single layer. Bake until crispy, 10 to 15 minutes. Pour the glaze over the bacon and cook another 10 minutes.
For the biscuits: In a food processor, combine the flour, sugar, salt, baking powder and butter. Pulse 2 to 3 times until the butter is roughly incorporated. Set aside.
Combine the buttermilk, egg, ginger and orange zest. Mix the wet and dry ingredients until just combined. Dump onto a floured surface and pat down into a square, about 1 inch high. Cut into desired shapes and place the other prepared sheet pan. Brush the top of each biscuit with buttermilk. Bake until the biscuits are a light golden brown, 8 to 10 minutes.
While the biscuits are cooking, start the gravy. Remove the casings from the sausage links. Heat a skillet over medium-high heat and saute the sausage, breaking it up in the pan until fully cooked.
In the meantime, in a saucepan, melt the butter over low heat. When melted, vigorously whisk in the flour. Continue to whisk the roux on medium heat for about 3 minutes. Add 2 cups chicken stock to the roux. Continue whisking until shimmering. If the gravy is too thick, add more stock until it reaches the desired consistency. Once at the desired consistency, add the sesame oil and chopped scallions. Add the sausage and season with salt and pepper. Hold warm over low heat.
For the mustard greens: In a large saute pan, heat the sesame oil and butter. When the butter is melted and foamy, add the mustard greens. Cook on high heat until tender and the greens begin to crisp, 7 to 8 minutes. Season with salt and pepper.
To serve, split open a biscuit, top with the gravy, follow with the mustard greens and garnish with a slice of the soy-glazed bacon.
