It’s Father’s Day on Sunday and, across the land, that means barbecue time! I’m often asked for Vegetarian BBQ recipe ideas, something tasty which can be popped on the grill and which won’t crumble to mush, so I jumped at the chance when Iceland asked me whether I could create a vegetarian barbecue recipe using their frozen products! May I present to you my newly developed Spiced Couscous and Sweet Potato Burgers?!

Vegetarian Couscous and Sweet Potato Burgers with tomato and corn on the cob.

I’ve recently discovered the power of a mashed sweet potato to hold a pie together, it forms the same function here and makes these burgers moist and delicious as only a sweet potato can! The giant couscous in Iceland’s couscous with vegetable mix added really good texture to this burger and the Moroccan Spice Blend gave it a subtle spiced flavour which worked really well as part of a traditional barbecue!

I added an egg to the sweet potato and couscous mix to hold it all together on the grill but I’m going to be trying them again with tahini for a vegan version – the sweet potato does such a good job I’m not convinced the egg is absolutely necessary! My burgers are such a perfect shape because I formed them using pastry cutters, you can just as easily make nice rustic burgers by shaping them with your hands.

Iceland have such a fabulous selection of frozen veg, veggie burgers and sausages that putting together a vegetarian Barbecue or alfresco dinner is really easy – the first hint of a ray of sunshine and you’re ready to go! I paired my homemade veggie burgers with the ever reliable Linda McCartney vegetarian sausages and frozen corn cobs which I defrosted on the hob and then bunged on the BBQ to char a bit, lovely! I also cooked up some Meditteranean Veg in a Basil Seasoning alongside Asparagus Spears with Salted Butter and Zesty Bean Quinoa all of which were a happy find in my local Iceland! I was pleasantly surprised at how reasonably priced all these ingredients were – it made for a fabulous Friday Feast!

What I really like about frozen food is the convenience of having something there at my fingertips, ready to go. I don’t have to worry that it might rain on my parade and everything will wilt waiting for summer to finally put in an appearance, I can grab the ingredients for a cracking meal the moment that sun has put his hat on – that’s the #poweroffrozen!
