Ingredients

• 1 lb / 450g squid rings, frozen
• 1 lb / 450g fresh spinach, torn
• 2 cups / 200g cauliflower, roughly chopped
• 4 tbsp / 60ml extra virgin olive oil, divided
• 2 tbsp / 30ml fresh lemon juice
• 1 tsp / 5g garlic paste
• 1 tsp / 1g dried rosemary, crushed
• 2 fresh thyme sprigs
• 1 tsp / 6g sea salt, or to taste
• 1 cup / 240ml water or fish stock

Instructions

1. Directions
2. Thaw the squid rings by placing them in a bowl of warm water for 10-15 minutes. Drain thoroughly in a colander and set aside.
3. Select the ‘’Sauté’’ function on your Instant Pot. Add 2 tbsp of olive oil. Once shimmering, add the garlic paste and rosemary, and stir-fry for 1 minute until fragrant. Add the spinach and a pinch of salt, cooking for 3-4 minutes until wilted. Remove spinach and set aside.
4. Add the remaining 2 tbsp of olive oil to the pot. Add the chopped cauliflower in an even layer, then top with the squid rings. Drizzle with lemon juice, sprinkle with salt, add the thyme sprigs, and pour in the water or fish stock.
5. Secure the lid and set the steam release to ‘’Sealing’’. Pressure cook on HIGH for 9 minutes.
6. When the cooking time is complete, perform a quick pressure release by carefully moving the valve to the ‘’Venting’’ position.
7. Once the pin has dropped, open the pot. Stir the reserved wilted spinach back into the mixture. Taste and adjust seasoning if desired.
8. Serve hot and enjoy immediately.
