Preheat oven to 200ºC (180ºC fan oven) and grease muffin tin holes with butter.
Add onion and carrot to the Thermomix bowl: 5 seconds, speed 5.
Add courgette, the yellow pepper, fresh coriander and the black pepper: 2 seconds, speed 5.
Add egg yolks and the dash of milk: 30 seconds, speed 3.
Pour the mixture into the muffin tin holes, it won't rise very much so you can fill them quite a bit but avoid going to the top, three quarters. Then bake for 10-15 minutes until cooked through. Enjoy with a coffee. In an air fryer, bake at 170ºC for 10 minutes and check.
Note: You could steam these in your Instant Pot or in the Varoma of course. In the Instant Pot pour 250 ml into the inner pot, trivet in place, silicone muffin cases or mini pudding tins filled with the mixture go on to of the trivet. Press Manual, programme 5 minutes and quick release for the silicone moulds, I'd allow a bit longer for mini pudding tins. Let me know how it goes!If using the Varoma, try using just boiled water from the kettle as otherwise it will take longer. They might need longer in the Varoma.
Tip: If you’re in a hurry, you can always turn it into tasty scrambled eggs or a delicious omelette once mixed. You know, because life is so unpredictable...
