Mashed peas and spinach with grilled tuna is an eye-catching dinner that’s packed with healthy fats - and is one of our favourite low carb recipes (opens in new tab).
The clean, green and healthy flavours pair beautifully with the full flavours of tuna steak in this dish. Mashed peas with spinach is a great alternative to mashed potatoes for when you want something a bit lighter. We’ve used butter beans to add extra texture and protein to this vibrant and healthy mash, but if you can’t find them, cannellini beans would also work. This simple dish of mashed peas and spinach with grilled tuna is a satisfying weeknight meal that you’ll want to make again and again.
