How to Make It

Step 1

Preheat the oven to 400 degrees Fahrenheit.

Step 2

Slice the zucchini into half inch slices. Heat the olive oil in a skillet over a medium heat and add the zucchini in an even layer. You can do this in two batches if required. Cook until browned on both sides.

Step 3

Arrange the browned zucchini in a small oven proof dish and sprinkle over half of the Italian seasoning and a little pinch of salt and pepper.

Step 4

Thinly slice the onion and slice the bell pepper flesh into half inch wide strips. Add to the skillet over a medium heat and cook for 2-3 minutes to soften.

Step 5

Scatter half the cheddar and half the mozzarella over the zucchini.

Step 6

Arrange the peppers and onion over the top and sprinkle over the remaining Italian seasoning and a pinch more salt and pepper.

Step 7

Scatter the remaining cheese over the top.

Step 8

Transfer to the oven to bake for 18-20 minutes or until the vegetables are tender and the cheese is golden and bubbling. Serve hot.
