In the bowl of a stand mixer, combine the sourdough starter, water, sugar, oil and bread flour, stirring with the flat beater or wire whip on low until a sticky dough (sponge) forms.
Cover the sponge and let it rest at room temperature for about 30 minutes.
Add the salt and all purpose flour (1/2 cup at a time) to the sponge and stir using the dough hook until the dough begins to pull away from the sides of the bowl.
Continue mixing the dough with the dough hook for 5 to 7 minutes or until the dough reaches a smooth, elastic consistency.
Place the dough into a large greased bowl, turning over to make sure all sides are oiled, and cover with a damp towel or plastic wrap.
Allow the dough to rise overnight in a warm place (right around 75 degrees if possible) until it is bubbly and has doubled in size.
Cut the dough in half to form two 5-by-7-inch rectangles.
Tightly roll each piece of dough on the long side, pinching the ends to seal them.
Place the dough on a parchment paper-lined baking sheet and cover with plastic wrap.
Let the dough rise for roughly 2 hours; the loaves should look puffy.
Preheat the oven to 400 degrees.
Using a sharp knife, score the loaves with 3 to 4 diagonal slashes about 1/4-inch deep.
Bake the loaves for 30 minutes or until they are golden brown on the outside and sound hollow when tapped.
Allow the loaves to cool completely before slicing.

In a large skillet, sauté the onions in bacon grease or oil until tender.
Add in the ground meat, sprinkle everything with Lawry’s and Adobo seasoning, and cook and break it up until browned; drain any excess grease.
Spread the meat into the bottom of a 9-by-13-inch baking dish (grease the sides if desired).
Evenly spread the frozen mixed vegetables over the meat.
Pour the gravy evenly over the vegetables.
Sprinkle the cheese evenly over the vegetable layer.
Using a rubber scraper, carefully spread the mashed potatoes over the top of the cheese, making sure it covers the entirety of the pan all the way to the edges.
Bake in the preheated oven for 30-40 minutes or until the mashed potatoes begin to brown.
Scoop onto plates or into bowls and serve with a salad or other preferred side dish.
