This grilled sandwich combines the savory flavors of grilled spam, fresh tomato, melted cheddar cheese, and crisp onion between buttery slices of bread. It's a quick and satisfying meal perfect for any time of the day.
While most of the ingredients in this recipe are common, grilled spam might not be a staple in every household. You can find spam in the canned meat section of your supermarket. Make sure to get a small onion and fresh tomato from the produce section, and don't forget the cheddar cheese from the dairy aisle.

Ingredients for Grilled Spam Tomato Cheddar Cheese and Onion Sandwich
Bread: Any type of bread you prefer will work for this recipe, such as white, whole wheat, or sourdough.
Grilled spam: Pre-cooked and sliced spam that adds a savory, salty flavor to the sandwich.
Tomato: Freshly sliced tomato adds a juicy, tangy element to the sandwich.
Cheddar cheese: Sliced cheddar cheese provides a rich, creamy texture and flavor.
Onion: Thinly sliced onion adds a bit of crunch and sharpness to the sandwich.
Butter: Softened butter is used to coat the bread slices for grilling, giving the sandwich a golden, crispy exterior.
Technique Tip for Making This Sandwich
To achieve the perfect grilled sandwich, ensure your butter is evenly spread on the bread slices. This will help create a uniform golden crust. When layering the ingredients, place the cheddar cheese directly on top of the grilled spam and beneath the onion and tomato slices. This positioning allows the cheese to melt more effectively, binding the other ingredients together and enhancing the overall flavor.

How to Store or Freeze This Sandwich
- Allow the sandwiches to cool to room temperature before storing. This prevents condensation, which can make the bread soggy.
- Wrap each sandwich individually in aluminum foil or plastic wrap to maintain freshness and prevent them from drying out.
- Place the wrapped sandwiches in an airtight container or a resealable plastic bag. This helps to keep out any unwanted odors from the fridge.
- Store the sandwiches in the refrigerator if you plan to consume them within 2-3 days. For longer storage, consider freezing.
- To freeze, place the wrapped sandwiches on a baking sheet in a single layer and freeze until solid. This prevents them from sticking together.
- Once frozen, transfer the sandwiches to a resealable freezer bag or airtight container. Label with the date to keep track of storage time.
- When ready to eat, thaw the sandwiches in the refrigerator overnight. For a quicker option, use the microwave's defrost setting.
- Reheat the sandwiches in a preheated oven at 350°F (175°C) for about 10-15 minutes or until heated through. Alternatively, use a toaster oven or grill pan to restore the crispy texture.
- Avoid reheating in the microwave if possible, as it can make the bread rubbery and the cheese less appealing.
- Enjoy your grilled spam tomato cheddar cheese and onion sandwich as if it were freshly made!
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Wrap the sandwich in aluminum foil to prevent it from drying out. Place it on a baking sheet and heat for about 10-15 minutes until the cheese is melted and the bread is warm and crispy.
Use a toaster oven for a quicker method. Set it to 350°F (175°C) and place the sandwich directly on the rack or on a small baking tray. Heat for 8-10 minutes, checking halfway to ensure even warming.
For a stovetop method, preheat a skillet over medium heat. Place the sandwich in the skillet and cover with a lid to trap the heat. Cook for about 3-4 minutes on each side, pressing down gently with a spatula to ensure the cheese melts evenly.
If you're in a hurry, use the microwave. Place the sandwich on a microwave-safe plate and cover with a damp paper towel to keep it moist. Heat on medium power for 1-2 minutes, checking halfway to avoid overheating.
For an air fryer method, preheat the air fryer to 350°F (175°C). Place the sandwich in the basket and heat for 5-7 minutes, flipping halfway through to ensure both sides are crispy and the cheese is melted.
Best Tools for Making This Sandwich

How to Save Time on Making This Sandwich

Use pre-sliced ingredients: Buy pre-sliced cheddar cheese and pre-sliced tomatoes to cut down on prep time.
