Easy Tuna Pasta Bake - tuna with pasta, peas and sweetcorn in a lovely creamy, cheesy sauce. It's an easy meal that everyone loves - made with mostly store-cupboard ingredients! Pasta, sweetcorn, tuna fish - all make up the bulk of the meal. Frozen peas are a great addition too - but you can use canned or fresh if you like. Apart from that, we're really just talking milk, cheese and a bit of butter from the fridge.
