You won't miss the bread one bit with these low-carb zucchini tuna melts.
- Pre-heat the oven to 400 degrees Fahrenheit.
- Trim the ends of the zucchini, cut in half lengthwise, and create a shallow channel down the center (a spoon works well for this). Drizzle with olive oil, season with salt and pepper, and roast for 10 minutes.
- Combine tuna, shallots, celery, lemon juice, salt, and pepper. Divide the tuna mixture evenly among the zucchini halves. Add the tomatoes and top with cheese.
- Broil for 1-2 minutes, or until the cheese is melted. Sprinkle with fresh herbs if desired. Serve Zucchini Tuna Melts hot and enjoy!
