Preheat oven to 350F
Spray a 9x13 baking dish with nonstick spray.
Place the bottom half of each slider roll in the bottom of the baking dish.
To assemble the sandwiches, start with a slice of cheese, then eggs (if using baked eggs, use 1 per roll. If using scrambled, just scoop a large spoonful onto each bun), then ham, sausage, bacon, and more cheese. Replace the tops to each slider roll.
In a small bowl, mix together the melted butter, mustard, poppy seeds, and garlic powder. Brush the top of each roll liberally with the butter mixture. I actually added it my the spoonfuls :)
Bake covered for 12 minutes and then remove cover. Continue cooking for another 4-6 minutes or until the bread is toasted and and the cheese fully melted.
Remove and serve!
NOTE: You can make these ahead. Just refrigerate overnight and bake when ready.
NOTE: I love the La Brea rolls for this because they're take and bake. This helps the rolls not to burn while in the oven. Perfection!
NOTE: If you don't like any of the ingredients, leave them out! These are awesome even if they're just egg and cheese. You can customize for each person! GO!
