1Preheat oven to 350°F. Spray or brush a 9-inch pie plate with olive oil. Heat tortillas for 20-30 seconds in the microwave or a hot dry skillet to soften them. Place one tortilla in the plate, fitting it in like a piecrust. Spray or brush tortilla with olive oil, then sprinkle with half the grated cheese. Fit the second tortilla over the first. Set aside.
2Cut bacon into ½-inch pieces. Cook bacon in a skillet until not quite crisp. Remove and drain on paper towels. In rendered bacon fat, cook onion until soft but not browned. Drain well.
3In a mixing bowl, stir together hominy, beaten eggs, cream, grated cheese, onion, salt, and pepper until well combined. Pour carefully into tortilla shell. Place sliced tomatoes in a single layer on top to cover pie. Top evenly with the bacon.
4Bake for 25-35 minutes, until eggs are set and tortillas are nicely browned. Check at 15 minutes, and cover edges with foil or a pie guard if tortilla browns too quickly. Allow to cool 15 minutes before slicing. Slice with sharp knife. May be served at room temperature.
