1. Spaghetti Sauce Grilled Cheese Sandwich

This sandwich brings comfort in every bite. Crispy bread with melted cheese and warm spaghetti sauce makes it rich and filling. Great for lunch or a quick dinner. Kids love the cheesy center, and it feels like pizza in sandwich form.

Ingredients

• 4 slices bread
• 1 cup leftover spaghetti sauce
• 4 slices mozzarella cheese
• 2 tbsp butter

Instructions

Start by placing a skillet on medium heat. Let it warm up for a few minutes. Spread butter on one side of each slice of bread. Keep the butter layer even so the bread turns golden while cooking.

Take one slice of bread and place it on a plate, butter side down. Add one slice of mozzarella cheese on top. Spoon a small amount of leftover spaghetti sauce over the cheese. Spread it gently but do not go too close to the edges. Too much sauce can make the sandwich soggy.

Place another slice of cheese over the sauce. Then cover with another slice of bread, butter side facing up. Repeat this for the second sandwich.

Move both sandwiches to the skillet. Let them cook slowly. Press lightly with a spatula so the bread crisps well. After about 3–4 minutes, check the bottom. It should look golden brown. Flip the sandwich carefully.

Cook the other side the same way. The cheese inside should melt fully. The sauce will warm up and blend with the cheese. Keep heat steady so nothing burns.

Remove from the skillet and place on a cutting board. Let it rest for one minute. Slice in half and serve warm.

Use a spoon to make small wells in the sauce. Crack one egg into each space. Keep the eggs separate so they cook evenly.

Cover the skillet with a lid. Let the eggs cook gently in the sauce. This step takes around 6–8 minutes. Check the eggs often. The whites should set, but the yolks can stay soft or firm based on preference.
