“To deepen flavours, always sauté your onions and garlic first before adding to the slow cooker. It adds a lovely caramelised note that slow cooking alone can’t achieve.”

• Try adding a splash of red wine or balsamic vinegar to your vegetarian chilli for a subtle tang.
• For a vegan stroganoff, substitute sour cream with coconut yogurt or a plant-based cream alternative.
• Mix in seasonal UK vegetables such as parsnips or butternut squash to your lentil curry for extra heartiness.
• Adjust the heat level by adding fresh chopped chillies or mild chili powder depending on your preference.
• Batch cook and freeze portions of these meals for quick weekday dinners.
