4 very large tomatoes (8 to 12 ounces each)
1 tablespoon olive oil, plus 2 teaspoons more for brushing
1/4 cup minced shallots
1 tablespoon flour
3/4 cup low-fat milk (1 percent)
One 10-ounce package frozen/defrosted spinach, squeezed of all excess liquid, then chopped (even if the frozen spinach was already chopped)
1 ounce (1/3 cup) finely grated Parmigiano-Reggiano cheese
1/4 teaspoon salt
1/4 teaspoon freshly ground black pepper
4 large eggs, at room temperature
Cut off the top of each tomato so you’ll be able to scoop out the contents. (You can discard the stems, cut up the tops and add them to the tomato flesh, if you like.) Use a melon baller to remove the insides of the tomatoes (reserve the tomato flesh), making sure to leave the shell of the tomato thick enough to form a sturdy cup.
Place the tomato insides into a fine-mesh strainer set over a bowl. Strain out and discard the seeds, and reserve 1/4 cup of the tomato water. Discard the tomato flesh or reserve for another use (such as a fresh tomato sauce).
Brush the outsides of the 4 hollowed-out tomatoes with 2 teaspoons of the oil. Place them on a parchment-paper-lined baking sheet.
Preheat the oven to 400 degrees.
Heat the remaining tablespoon of oil in a medium skillet over medium heat. Once the oil shimmers, stir in the shallots; cook for about 2 minutes or until they are translucent, then add the flour and stir for 30 to 45 seconds. Whisk in the milk and the reserved 1/4 cup of tomato water; once the mixture starts to bubble, cook for 3 or 4 minutes, until it has thickened.
Add the spinach and cook for 1 to 2 minutes, stirring, to form a thick, creamy sauce. Stir in half of the Parmigiano-Reggiano cheese and the salt and pepper. Turn off the heat.
Fill each tomato cup about halfway with the creamed spinach, forming a well in the center of the spinach and pushing the spinach all the way up the inner sides of the tomatoes. Be sure to leave enough room in each tomato cup for an egg. (You may have some leftover spinach, depending on the size of your tomatoes. If so, reserve for another use.)
Working with one at a time, crack each egg into a small bowl, then carefully slip it into the center of a spinach well. Sprinkle with the remaining Parmigiano-Reggiano cheese. Bake for 18 to 22 minutes or until the egg whites are just set, the yolks still seem runny and the cheese has melted.
MAKE AHEAD: The tomatoes and creamed spinach may be covered (separately) and refrigerated several hours in advance. You may have a few tablespoons of the creamed spinach left over, depending on the size of your tomatoes.
