Step 1

Put the kettle on. Fill one-third of a large saucepan with water and place over high heat. Cover and bring to the boil.

While the water heats up, cut tomatoes in half, slice the avocado and cut the tortillas into thin strips. Thinly slice the shallots.

Step 3

Pour the boiling water from the kettle into the pan of hot water. Cover and return to the boil. Add the pasta and cook following packet directions for 2 minutes less than stated on the packet. Drain.

Step 4

While the pasta cooks, add oil to a frying pan to come 1cm up the side of the pan. Heat over medium heat. Add the tortilla strips and cook for 1-2 minutes or until golden. Transfer to a plate lined with paper towel to drain.

Step 5

Place the pasta, tomato, corn, beans and peppers in a large serving bowl and toss to combine. Coarsely chop coriander leaves. Add to bowl. Toss until well combined. Top with avocado, tortilla strips and a dollop of sour cream. Season and serve.
