Place your baking sheet in the oven and position a rack in the second lowest slot. Preheat the oven to 260°C (500°F). It's important to preheat the oven now, as it will take some time to reach the desired temperature.
In a small bowl, combine warm water, ½ tsp sugar, and instant yeast. Stir until combined, then cover the bowl with a lid or towel. Set aside for 5 minutes. The yeast is ready when it starts to bubble.
In a large mixing bowl, combine 1 cup of all-purpose flour, 1 tsp sugar, and salt. Mix until combined.
Pour the yeast mixture into the dry ingredients. Stir with chopsticks or a fork until combined, forming a wet dough.
Add 2 tbsp olive oil and ½ cup of all-purpose flour to the wet dough. Mix until the dough fully incorporates the flour. The dough will still be sticky, so using chopsticks or a fork can help.
Add the remaining ½ cup of all-purpose flour to the dough. Use your hands to knead the dough until it is smooth and slightly sticky but not sticking to your hands. If kneading in the bowl is difficult, transfer the dough to a lightly floured surface. The dough is ready when it springs back slightly when touched. Shape the dough into a round ball.
Grease a separate bowl with olive oil. Roll the pizza dough inside the bowl until it is coated with olive oil. Cover the bowl with plastic wrap and place it in a warm area. Allow the dough to rise for 30 minutes or until doubled in size.
The dough has finished rising when it doesn't spring back after being poked. Punch out the air to deflate the dough, then transfer it to a lightly floured surface. Knead briefly until smooth (about 3-5 times). Divide the dough into 4 equal pieces, or keep it as one large (approximately 12") pizza.
Use your hands or a rolling pin to shape the dough into a round or oval (or any desired shape). Ensure to punch out the air before rolling the dough into a thin sheet.
Carefully remove the baking sheet from the oven and transfer the dough to it. Pinch or fold the edges to form a crust.
Drizzle additional olive oil over the pizza. Brush the entire surface, including the crust, with olive oil. Be generous on the crust to achieve a beautiful golden brown color during baking.
Poke holes all over the center of the pizza with a fork to prevent the dough from bubbling up in the oven.
Top with spinach, shredded mozzarella, bacon slices, and cherry tomatoes, leaving the center open for the egg. Gently break an egg into the center of each dough piece.
Bake for 8-10 minutes, until the crust is golden and the egg is set. Season with salt and pepper. For a large pizza, bake for 10-12 minutes instead.
