Step 1

Wash the tomatoes and pepper, peel the onions and cut them all into thin slices - the cheese too.

Step 2

Wash the spinach and let it drain in a sieve.

Step 3

Grab a tortilla and spread a layer of pesto over half of it. A tablespoon works well.

Step 4

Add a light layer of cheese on top and a quarter of the tomato, pepper and onion, followed by a few spinach leaves.

Step 5

Top it with another layer of cheese.

Step 6

Then fold the other half of the tortilla on top and place in a large frying pan (nonstick).

Step 7

Heat for 2-3 minutes. Flip and heat for another 2-3 minutes until the cheese has melted - a good indicator is a little running out the side.

Step 8

Pro Tip: place a heavy pot on top of the quesadilla so that it flattens nicely and cooks more evenly - this will also stop the insides escaping! If you don't like the thought of putting a pot directly on your quesadillas then put a plate between the two.
