Heat olive oil in a non-stick pan over medium heat.
½ Tablespoon olive oil
Add the spinach, minced garlic, and sauté for 5–6 minutes until it wilts. Sprinkle with a pinch of salt, give it a quick stir, then transfer the spinach to a plate. Wipe the pan clean with a paper towel.
Spread butter on one side of each slice of bread. Place two slices in the pan, butter side down.
4 Slices Bread, 2 Tablespoons Butter
Add chopped sun-dried tomatoes on each slice and press them lightly into the bread using the back of a spoon. Top with half of the crumbled feta, half of the shredded cheddar, and the sautéed spinach. Add the remaining feta and cheddar on top of the spinach. Sprinkle with oregano and chili flakes.
Close each sandwich with the remaining bread slices, butter side up.
Place the pan over medium heat and cook for about 4–5 minutes, or until the bottom is golden and crisp. Flip carefully and cook the other side for another 4–5 minutes, until both sides are toasted and the cheese is melted.
Optional: Sprinkle extra oregano or chili flakes on top and drizzle with honey for a sweet finish. Serve immediately while warm and melty.
Notes
Tips & Tricks for the Best Grilled Cheese
Use thick-cut bread like sourdough or ciabatta—it holds up well and crisps beautifully.
Make sure your spinach isn’t watery before adding it to the sandwich to avoid sogginess.
You can easily swap in mozzarella or provolone if you want a milder, meltier cheese.
Add-ins like olives, caramelized onions, or even a slice of tomato make great customizations.
