Lentils are such fabulous little things – I cook with one or other of them at least twice a week and they are perfect in these vegan Green Lentil Burgers.

Green Lentil and Sweet Potato Burgers in a homemade bun.

The burger buns are homemade too, as is that glorious sweet pepper sauce, I was on a roll that day 😉

I’m on the hunt for the perfect vegan burger recipe but I’ve loved every one I’ve made so far and haven’t yet got a favourite! This one is deeply savoury and happy to carry all the traditional burger relishes and accoutrements. It’s also really easy to make and holds together nicely in the oven. They work really well on the BBQ, just turn them carefully rather than flipping them with abandon.

I served my burgers in homemade vegan rolls with crisp salad leaves and my sweet red pepper sauce. I can’t really call my recipe for pepper sauce a ‘recipe’, it’s too simple to merit the title, but it always impresses anyone who tries it so please don’t tell anyone else how easy it is! To make it all you need is one whole, roasted and skinned red pepper (I use jarred peppers from Peppadew to make the whole process really speedy), 1/3 cup canned chopped tomatoes, salt and pepper. Whizz it all up in a blender and you’re done! I also made a tray full of homemade chunky chips – well, the oven was on, it would be rude not to! Just potatoes, chopped into thick slices, parboiled, drained, drizzled with olive oil, sprinkled with sea salt then roasted for 30 – 40 minutes….Mmmmm.

My eldest is due home from University in Berlin next week and we will be rushing around like mad things. It’s a very quick turnaround between leaving Berlin after 7 months and heading to Tokyo to study there for 5 months! I’ve just sent him a picture of this burger and he’s keen to taste test it when he gets back so at least that’s one thing sorted!
