Roasted Onion Vegan Gravy

• 1 tablespoon vegetable oil
• 1 large yellow onion, skin on and halved
• 1 small carrot

Heat a large heavy-based saucepan on the stove; add the oil and heat to hot, not burning. Place the two halves of onion cut side down and roast to caramelise the sugars in the onion without burning, this will take about 10 minutes.

Add the chopped vegetable to the pan and stir well and cook for five minutes. Add the water and simmer for 20 minutes to cook the vegetables.
