Then add finely chopped veggies, 1 tbsp of green bell pepper, 1 tbsp of tomatoes, 1 tsp coriander leaves, ½ tsp basil leaves, and ¼ tsp oregano. Mix it well. Lastly, add grated cheese and give it a quick stir.
Microwave it for about 1 minute and 50 seconds. Garnish the frittata with some coriander leaves, olives, and grated cheese.
