Day 34: Halloumi, Roasted Pepper, Red Onion & Harissa Sandwich

Day 34: Halloumi, Roasted Pepper, Red Onion & Harissa Sandwich

inspired by Mildreds

Yup today I’m writing about a cheese sandwich. Thought I needed something a bit more straightforward after that venison dish yesterday.

But this is no ordinary cheese sandwich.

Oh no! I’ve started sounding like an M&S advert. Is this a new lockdown symptom? Moving on. Quickly.

So it’s another meat free Monday and time for me to talk about the first vegetarian restaurant I ever went to. Mildreds in Soho.

I was a vegetarian for nine years, from the age of 11 to 20. Growing up in Warwickshire there weren’t any vegetarian restaurants near me. But when I moved to London in 2006 that all changed. I’ll never forget going to Mildreds for the first time. Sitting in a restaurant and looking at the menu.

I could order anything!

In those days most menus were not as veggie friendly as they are now. There was usually only one option. Probably a stuffed pepper. Or something with mushrooms. Perhaps mushrooms stuffed in a pepper. The possibilities were not endless.

But having to choose from a whole menu? This had never happened to me before! It took me ages to order. I think the waiter got a bit fed up!

I’ve been back to Mildreds in Soho countless times since. They also have sites in Dalston and Kings Cross now too. Which is great because the queue for the Soho restaurant seems to get a bit longer every time I go! But that’s not going to stop me.

However much I love exploring new dishes, there are a couple of old favourites I go back to time and time again. One is their crumble that’s served with vegan custard (I’m not sure how they make custard that good without dairy, but they do!)

And the other is their halloumi burger. Or sandwich, depending on how you look at it.

It’s normally served in between flat bread. I think that makes it a sandwich. And today this is going to be my lunch. Aidan’s at work so I’m making it just for me. I can eat a whole block of halloumi without anyone there to judge (or even worse, share).

This doesn’t seem to be on their restaurant menus at the moment so I have to do a bit of internet digging to find the one I ate. And this is it…

“Halloumi with charred red pepper, red onion, romaine lettuce, tahini & harissa in flatbread”

Perfect. I love a dish description that basically tells you everything that goes into it.

Firstly, red onions and peppers go into the oven to roast. Next flatbreads are made with the easy yoghurt and flour recipe. Then halloumi is fried. Half goes in the sandwich and half just goes straight in my mouth. No one there to stop me!

Now just to stack it all up and tuck in! It makes a pretty generous lunch for one (not even counting the extra halloumi I ate) but I don’t care. It’s amazing.

This really is no ordinary sandwich. I realise an ordinary sandwich wouldn’t generate this much washing up.

But it was totally worth it.

Prep Time 15 mins
Cook Time 20 mins
Total Time 35 mins
Course Main Course
Servings 1 person


  • 1 red pepper
  • 1 red onion
  • ½ block halloumi
  • 1 tbsp tahini
  • 1 tsp harissa
  • 1 handful lettuce
  • olive oil
  • 100 g self raising flour
  • 100 g natural yoghurt


  • Preheat the oven to 200°C
  • Cut the onion into wedges and the pepper into quarters. Place on a baking tray and season. Drizzle with olive oil. Put in the oven to roast for about 20 minutes. You want the veg to be charred aound the edges.
  • To make the flatbreads mix the flour and yoghurt together in a bowl. It should form a sticky dough. Generously flour a work surface and divide the dough in half. Using your hands flatten each piece of dough and pull out to roughly the size of a pitta bread.
  • Heat a non stick pan on a high heat. Fry the flatbreads for 2-3 minutes on each side until they have puffed up and have turned brown. Brush with olive oil and leave to cool.
  • Cut the halloumi into slices. Fry in a non stick pan on a medium high heat until golden on both sides.
  • Now assemble the sandwich. Take one flatbread and spread over half the tahini. Then add the lettuce peppers and onions. Top with the halloumi. Now spread over the other half of the tahini and the harissa. Add extra harissa if you want more of a spicy kick. Place the other flatbread on top and now enjoy!
