Marmite, avocado and mushroom toastie
Combining avocado and tomatoes with marmite and mushrooms makes this toastie a bit different, but full of unexpected and delicious flavour combinations. The combination of salty, fatty, and juicy really is the key to a successful sandwich. Ideal if you’re trying to include more plants in your diet, but still want to enjoy a midday sandwich. This works perfectly for breakfast, lunch or a snack!
All you’ll need is:
-
Bread
-
Marmite
-
Avocado
-
Mushrooms
-
Cherry tomatoes
-
Coriander
-
Hot sauce or chilli flakes (optional)
Start by chopping up the mushrooms and frying in a pan with a little olive oil, and salt and pepper until they’re reduced.
Meanwhile, spread vegan butter (my favourite is Naturli) on your bread on all four sides, and top one side with Marmite for saltiness. The Marmite makes this the perfect choice for breakfast too – I am a lover of Marmite, and have been since I was very little.
Now you can layer up the toastie, starting with the freshly sliced avocado, along with a squeeze of lemon juice to bring out the flavours. When your mushrooms are ready add them onto the avocado, and then top with the tomatoes.
Season with salt and pepper, add coriander, and then drizzle with an optional splash of hot sauce or a few chilli flakes (highly recommended – avocado and spice go hand in hand). Close the sandwich with the other slice.
