2 Caramelise onion
Heat a non-stick pan over a medium-high heat with a drizzle of oil. Once hot, add the onion with a pinch of salt and fry for 5 min. Once starting to brown, lower the heat to medium and add the garlic, brown sugar, balsamic vinegar and thyme. Cook for 10 min further, stirring frequently, until the onions start to soften.
