Ingredients
Sauce
- 1 cup hot water
- ½ cup cashews salted or unsalted
- 1 tablespoon lemon juice or raw apple cider vinegar
- 2 teaspoons sea salt
- ½ teaspoon black pepper
- 1 teaspoon dried dill
- ½ cup chicken broth
Veggies & Tuna
- 1 tablespoon ghee or coconut oil
- 1 medium yellow onion peeled & diced
- 2 medium celery stalks diced
- 3 medium garlic cloves peeled & minced
- 1 teaspoon sea salt
- ½ teaspoon black pepper
- 1 medium spaghetti squash cooked & skin removed
- 10 ounce of water-packed tuna two 5 oz cans, drained
- 1 tablespoon coconut aminos
- 1 tablespoon capers
- ¼ cup fresh parsley minced
- 2 tablespoons arrowroot powder
- Optional Garnish:
- ¼ cup fresh parsley minced
Instructions
- Oven roast your spaghetti squash by halving, removing its seeds and placing on a baking tray in the oven until very soft, about 45 minutes. When soft, carefully shred the squash onto a cutting board. Alternatively, cook in your electric pressure cooker set on the steam trivet with 1 cup of water on Manual at high pressure with the steam valve sealed for 7 minutes. Release steam after the timer goes off being careful not to burn your hands when removing the squash from the pressure cooker. Carefully shred the squash onto a cutting board.
- ADD hot water and cashews to a blender and allow to soak for 10 minutes.
- ADD ghee or coconut oil to a large stockpot or Dutch oven and bring to medium-low heat. Add diced onion, diced celery, minced garlic, sea salt, pepper and dried dill and sauté until soft, about 10 minutes.
- ADD the remaining sauce ingredients to your blender and blend on high until everything is completely combined. It will have a very thin texture.
- ADD shredded spaghetti squash to your pot of veggies and gently combine, breaking up the squash “noodles”.
- ADD your drained tuna and gently combine with the veggies.
- POUR your sauce into the pot and stir well. With the heat reduced to low, stir in arrowroot powder. This will thicken the sauce substantially.
- STIR in coconut aminos, capers and minced parsley.
- HEAT your oven’s broiler and if needed, transfer your casserole to an oven-proof baking dish. Heat under the broiler until the top has formed a golden crust, about 2 minutes, checking after a minute or so to prevent burning.
- Carefully REMOVE from your oven and allow to cool for a few minutes before serving, garnishing with optional minced parsley.
- SERVE, storing any leftovers in a glass container in the fridge for 3 days.
- ENJOY!
