Preheat the oven to moderate heat (170C fan forced)

Chop up the zucchini, red onion, carrot, potatoes and broccoli into small pieces (around 2cm long for the carrots and 3cm long for the rest)

Spread these out onto a baking tray, drizzle with the olive oil, and place in the oven to bake for 35-40 minutes or until cooked through (check them about 20 mins in and turn/mix them up to get a nice even bake)

Bring a pot of water to the boil and cook the pasta for 10 minutes or until cooked through

Once the pasta is cooked, drain the water off and add the tin of tomatoes, tomato paste and tuna to the pasta and stir through

Once the veggies are baked add these and the pasta mixture to a large, deep baking dish and stir to combine

Spread the grated cheese over the top and bake for 10-15 minutes or until the cheese is melted, slice into 5 serves

(Optional) squeeze lemon juice over each slice of tuna bake
