You can prepare the above steps in advance and follow the below steps before serving.
Preheat the oven to 350 F. Line a baking sheet with a parchment paper.
Remove the crust and butter bread slices.
Cut each bread slice into 4 square pieces.
Spread ½ – ¾ teaspoon of vegetable mixture on the canapes.
Place bread slices or canapes on a lined baking tray. Top them off with grated cheese.
Bake in 350 F oven for 6-8 minutes or until the cheese melts on the canapes. If there is some excess cheese on the baking sheet, that should turn golden brown.
Temperature of ovens vary. Hence check the canapes 6 minutes into baking and bake for another 2 minutes until cheese melts. Serve hot.
