The main topping is obviously cheese but there are many other ingredients that are easy to experiment with. The most common are: Onions Peppers Chillies Olives Beans Sweetcorn Tomatoes Avocado Cheese Salsa Minced meat Additionally, you can serve nachos with different types of dips, guacamole or sour cream. One thing I discovered and it really tastes great with nachos is my homemade basil pesto. I just spoon a few little drops over the nachos on my plate to take this meal to another level.   A great tip for quick toppings is to use leftover tomato sauce or bolognese sauce. I don’t really cook any sauces exclusively for this recipe. I learnt to plan our meals in advance and cook in bigger batches. I make a big pot of bolognese sauce that covers at least 2 of our dinners. Spaghetti bolognese is usually the first option. For the other half, it’s easy to convert bolognese into chilli con carne or like in this recipe to use leftovers as a topping for nachos.
