Garlic, Chilli and Lemon King Prawn Linguine
When you’re short on time but still want something absolutely delicious, prawns are hard to beat. They cook in just a few minutes and work wonderfully with simple Mediterranean ingredients like garlic, chilli and fresh herbs. The result is a vibrant pasta dish that really gives those holiday feelings.
Using fresh prawns ensures a particularly sweet and succulent flavour, but frozen will also work in a pinch! Essential is that generous squeeze of lemon just before serving and you’ll have a quick dinner that’s fresh, satisfying and perfect for sharing on a sunny evening.

Ingredients
- 250g king prawns
- 200g linguine
- 2 - 4 garlic cloves depending on taste!
- 1 tsp chilli flakes
- 2 tbsp olive oil
- 200g cherry tomatoes
- Small handful of flat-leaf parsley
- Zest of 1 lemon
- Juice of ½ lemon
- Salt and ground black pepper
- 25g freshly grated parmesan
Method
- Bring a large pan of salted water to the boil and cook the linguine according to the packet instructions (usually 9 - 11 minutes)
- Meanwhile, heat 2 tbsp olive oil in a large frying pan over a medium heat. Add the garlic and chilli flakes and cook gently for around 30 seconds until fragrant
- Add the king prawns and cook for 2-3 minutes, turning once, until they’re cooked and pink through
- Stir in the halved cherry tomatoes and cook for another 2 minutes, just until they begin to soften
- Drain the pasta, reserving a splash of the cooking water. Add the linguine to the pan with the chopped parsley, lemon zest and the lemon juice. Toss everything together, adding some of the pasta water to loosen the sauce
- Season with salt and pepper, finish grated parmesan if using

Seared Tuna Steaks with Sesame Soy Greens
Not only are fresh tuna steaks unbelievably meaty and tender, but they are incredibly quick to cook! A hot pan, a minute or two on each side and dinner is ready. Keeping the centre beautifully pink allows the tuna to stay super tender and full of flavour.
The sesame vegetables add freshness and crunch, with the soy giving that umami goodness, while microwave rice keeps the whole meal comfortably within 20 minutes.

- Sear the tuna for 1-2 minutes on each side for a rare centre, or 2-3 minutes if you prefer it a bit more well done

Simple Pan-fried Sea Bass with Lemon Butter and New Potatoes
Sea bass is one of those fish that prove that simple cooking is often the best. With beautifully crisp skin and delicate white flesh, it needs very little to let its natural flavour shine. Get ready for a restaurant-worthy meal without spending hours in the kitchen.
This recipe is ideal for warm summer nights when you want something light yet satisfying. Paired with buttery potatoes and seasonal green veg with a bit of bite, it’s a healthy, balanced meal with a fish that’s easy to master.

Ingredients
- 2 sea bass fillets

- 150g green beans or asparagus
- 25g unsalted butter
- 1 tbsp extra virgin olive oil
- Juice of ½ lemon
- Small handful fresh flat-leaf parsley, finely chopped
- Salt and freshly ground black pepper
- Lemon wedges, to serve
Method
- Bring a pan of salted water to the boil and cook the baby new potatoes for 12–15 minutes, or until tender. Add the green beans or asparagus for the final 3–4 minutes of cooking
- Meanwhile, pat the sea bass fillets dry with kitchen paper and season both sides with salt and freshly ground black pepper
- Heat the olive oil in a large non-stick frying pan over a medium-high heat. Place the sea bass skin-side down and press gently with a spatula for 20–30 seconds to stop the skin curling
- Cook for 4–5 minutes until the skin is crisp and golden. Carefully turn the fillets and cook for a further 1 minute, or until the flesh is just cooked through
- Remove the fish from the pan and keep warm. Reduce the heat slightly, then add the butter, lemon juice and chopped parsley to the same pan. Stir until the butter has melted and the sauce is well combined
- Drain the potatoes and vegetables, then divide between two plates. Top with the sea bass and spoon over the warm lemon butter sauce
- Serve immediately with extra lemon wedges on the side
Adam’s Tip: "Always cook sea bass skin-side down for most of the cooking time. It gives you beautifully crisp skin while keeping the flesh moist and delicate.”
