The salad of my childhood was generally some well soaked lettuce, slices of cucumber and quarters of tomato arranged on a platter. If my grandmother deemed it a special occasion there might be some quartered hard boiled egg too.

I spent over 20 years thinking that was what salad always was.  Not until I was let loose in the 1990s and discovered the delights of olive oils and capers did I realise that a salad could comprise pretty much anything so long as part of it was raw.

The only cheese in my grandma’s house was yellow and in rubbery slices, I’m not sure what she’d have made of dinky cubes of salty white Apetina!

Whether you want to rock your rocket or groove your greens with herbs, garlic or sundried tomatoes, Apetina can help put the oomph back in your salad.

Red Onion Tarts with Feta

Servings: 4

Equipment

• baking sheet lined with parchment paper
• 7cm tart cutter I used a crinkled one

Ingredients

• 3 red onions finely sliced into half moons
• 2 tbsp olive oil infused with garlic - or plain
• 3 tbsp soft light brown sugar
• 1 pack puff pastry pre-rolled
• 2 tbsp milk
• 1/2 tsp salt
• 25 g rocket fresh
• 100 g red peppers marinaded in oil
• 1 tbsp olive oil extra - for the dressing
• 1 tbsp balsamic vinegar for the dressing

Instructions

• Preheat the oven to 220c or gas 7.  
• Using a medium size saucepan, heat the olive oil and cook the onion on a low to moderate heat for five minutes. Add a splash of water if the pan dries and as the onion starts to soften replace the lid and turn the heat down to cook the onions for around 20 minutes.
• When the onions are fully softened stir in the sugar and salt allowing it to dissolve. Turn off the heat and set aside.
• Unroll the puff pastry and cut 12 circles with the round cutter. Lay them on the baking sheet lined with baking parchment paper. Paint the edges of the pastry circles with milk and spoon a dessert spoon of caramelised red onion into the centre of each circle. Bake for 12 minutes until lightly golden.
• Remove the tartlets from the oven and reduce the oven temperature to 180c / Gas 4. Dot 2-3 cubes of Apetina over each tartlet and return to the oven for 3-4 minutes until softened slightly.
• Meanwhile scatter rocket and slices of marinaded red pepper into a small bowl. Mix a vinagrette with the olive oil and balsamic vinegar, toss the rocket and peppers in this. Turn onto a salad platter and arrange the warm tartlets on top. Serve immediately.

Notes

Variations:

• You can buy ready-made caramelised onion jam to save time.
• You can use ready-made vol-au-vent cases rather than cut out circles of puff pastry.
