For the salsa: Combine the cilantro, tomatoes, jalapenos, onions and lime juice in a mixing bowl. Season with salt and pepper and toss to combine. Cover with plastic wrap and refrigerate until ready to serve.
For the burrito: Put the bacon in a large skillet over medium heat and cook until crispy and most of the fat has been rendered, stirring occasionally, 15 to 18 minutes. Transfer to a paper-towel-lined plate to absorb any excess fat, and reserve. Remove all but 2 tablespoons of the fat from the skillet and reduce the heat to medium-low. Slowly whisk in the flour, scraping up any browned bits on the bottom of the pan. Cook until the flour has turned light brown, whisking constantly, 3 to 5 minutes. Slowly whisk in the milk and bring to a boil over medium-high heat. Then reduce to a simmer and cook, stirring frequently, until the sauce is thickened to the consistency of gravy, 8 to 10 minutes. Season with salt and pepper. Turn off the heat, cover with a lid and set aside. Reheat later if necessary over low heat, scraping the sides and stirring to prevent lumps. Thin out the gravy with additional milk if it gets too thick.
Preheat the oven to 350 degrees F.
Heat the canola oil in a large nonstick skillet over medium-high heat. Carefully place the sausage patties in the hot skillet. Cook until browned on the first side, 2 to 3 minutes. Flip and cook the other side until browned and cooked through, 2 to 3 minutes. Transfer the cooked sausage to a cutting board. Reduce the heat to medium, pour the fat from the skillet into a small bowl, and wipe out the skillet with a dish towel. Roughly chop the sausage patties into 1-inch pieces. Reserve. Whisk the eggs with 1 teaspoon salt and 1/8 teaspoon pepper in a large mixing bowl. Add 2 tablespoons of the reserved sausage fat back to the skillet, swirling to coat. Add the eggs. Cook, stirring occasionally until large curds form and the eggs are set, 3 to 5 minutes. Transfer to a large bowl or plate.
To assemble, place the warmed tortillas on a flat surface. In the center of each tortilla, evenly layer the bacon, sausage patties, scrambled eggs, Cheddar, 1 hash brown patty, onions and green bell peppers. Finish with either the country gravy, fresh salsa, or a combination of both. Fold the part of the tortilla that is closest to you over the filling tightly. Fold over both sides of the tortilla and roll over tightly into a large burrito. Repeat this process with the 5 remaining burritos. Place the burritos on a large baking sheet seam-side down. Place in the oven for 10 minutes. Serve immediately with any extra country gravy and fresh salsa on the side.
