Recipe Information
Ingredients
- 2 medium-sized zucchini
- 2 tablespoons olive oil
- 5 ounces canned tuna
- 2 tablespoons mayonnaise
- 1 teaspoon dijon mustard
- 1 rib (finely chopped) celery
- 1 tablespoon (finely chopped) red onion
- 1 teaspoon garlic powder
- 0.5 teaspoon salt
- 0.25 teaspoon black pepper
- 1 cup shredded cheddar cheese
- 1 tablespoon (optional, for garnish) fresh parsley
Instructions
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Wash the zucchinis and slice them lengthwise into 1/4-inch thick long slices. You should have about 6-8 slices.
Place the zucchini slices on the baking sheet and brush both sides with olive oil. Sprinkle lightly with salt and black pepper.
Bake the zucchini slices in the preheated oven for 8-10 minutes, until they begin to soften but aren't mushy.
While the zucchini is baking, prepare the tuna mixture. In a medium-sized bowl, combine the canned tuna (drained), mayonnaise, dijon mustard, chopped celery, red onion, garlic powder, salt, and pepper. Mix thoroughly until well combined.
Remove the zucchini slices from the oven and carefully spread a generous layer of the tuna mixture on each slice.
Top each tuna-covered zucchini slice with shredded cheddar cheese.
Return the baking sheet to the oven and bake for an additional 5-7 minutes, or until the cheese is melted and bubbly.
Optional: Garnish with freshly chopped parsley for added flavor and presentation.
Serve immediately and enjoy your Low Carb Tuna Melt on Zucchini!
