Not Your Average Tuna Pasta Bake

What sets this Syn Free Tuna Pasta Bake aside from other recipes you might find out there, is that it goes beyond just stirring some sauce, tuna and pasta together and plopping it in to bake. By cooking up the fresh vegetables you add a greater depth of flavour, whilst adding in more texture and some delicious hidden veggies. For me, a simple dish like this doesn’t have to be boring or bog standard, it can be elevated with some simple cooking techniques and a little bit of love.

Totally Syn Free on Slimming World

As the name of this dish suggests, it is a totally syn free recipe! As long as you count the cheese as your Healthy Extra A choice, you can slot this syn free tuna pasta bake easily into your weekly meal plan. Whilst it is full of speed food, with the cherry tomatoes, onion and passata, I’d suggest pairing it with a healthy salad for extra speed food, or enjoying it with some steamed broccoli or green beans to keep yourself nice and full.
