1. Crank your oven to 375°F (190°C). Grease a standard 6-cup muffin tin really well with non-stick cooking spray—get into every corner.
2. In a bowl, whisk together the eggs, milk, salt, and pepper until well combined and slightly frothy. Stir in the bell peppers, onions, tomatoes, and shredded cheddar cheese until everything’s evenly distributed.
3. Let your bread sit at room temperature for a few minutes if it’s been in the fridge. Use a rolling pin to flatten each slice until it’s about half its original thickness—thin but not see-through.
4. Brush both sides of each flattened bread slice generously with melted butter, making sure you get edge-to-edge coverage.
5. Press each buttered bread slice firmly into a muffin cup, creating a cup shape with the corners sticking up slightly. Really press down on the bottom and sides to eliminate air pockets.
6. Divide the egg mixture evenly among the bread cups using a ladle or measuring cup—fill them about 3/4 full because they’ll puff up slightly while baking.
7. Slide the tin into the preheated oven and bake for 20-25 minutes until the eggs are completely set and the bread edges are golden brown and crispy.
8. Let the breakfast bombs cool in the tin for about 5 minutes—this cooling time is crucial for easy removal.
9. Run a butter knife around the edges if needed, then carefully lift out your breakfast bombs and serve warm—if you can wait that long!
