Preheat your oven to the grill setting (UK) or broiler setting (US). Set the temperature to 230°C/450°F.
Whilst the oven is preheating, chop the vegetables and grate the cheese.
Generously butter the 2 slices of bread and place them on a baking tray, butter side up.
Grill/broil your bread until it is golden brown. This should take 3-5 minutes, but keep an eye on it as it may burn quickly!
Remove the tray from the oven and flip the toast over so the golden buttered side is facing down. Top the bread with the diced onion, peppers, tomatoes and green chillies, spreading them out evenly.
Add the grated cheese on top of the vegetables, ensuring the bread is evenly covered with vegetables and cheese.
Grill/broil the bread again for 3-5 minutes, until the cheese is bubbly and melted.
Remove from the oven and serve immediately. If you wish, you can garnish the toast with chilli flakes for some extra heat. Enjoy!
Notes
You can use any cheese that melts well in this recipe.
Feel free to add extra veggies such as diced mushrooms, spinach, olives or sweetcorn kernels.
Leftovers can be stored in the fridge wrapped in foil to enjoy hot or cold the next day. To reheat, place the chilli cheese toast on a baking tray and heat in the oven for 5 minutes at 160°C/320°F or until fully heated through.
