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
Directions
Step 1
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Step 2
Wash the zucchinis and slice them lengthwise into 1/4-inch thick long slices. You should have about 6-8 slices.
Step 3
Place the zucchini slices on the baking sheet and brush both sides with olive oil. Sprinkle lightly with salt and black pepper.
Step 4
Bake the zucchini slices in the preheated oven for 8-10 minutes, until they begin to soften but aren't mushy.
Step 5
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.
Step 6
Remove the zucchini slices from the oven and carefully spread a generous layer of the tuna mixture on each slice.
Step 7
Top each tuna-covered zucchini slice with shredded cheddar cheese.
Step 8
Return the baking sheet to the oven and bake for an additional 5-7 minutes, or until the cheese is melted and bubbly.
Step 9
Optional: Garnish with freshly chopped parsley for added flavor and presentation.
Step 10
Serve immediately and enjoy your Low Carb Tuna Melt on Zucchini!
