Not sure that was the right recipe Ali. Maybe
BeeAnn, if it is muffins you are after then that's the recipe - worth making some even if it wasn't what you were looking for. We love mini muffins (sweet potato, bananas, sultanas and vanilla - yum!) I think lemonthyme has a few muffin recipes on her blog then you can experiment for yourself too.
If it is FRITATA you are looking for, ie an eggy thing, I think Lemonthyme's recipe uses ramekins rather than a mini muffin tray. You could use Ali's link to look through the other recipes to see if you can find it.
Basically 1 egg per ramekin for a single serving (it will fit perfectly and rise lovely). Add a few bits of veggies, I would pre-cook things like mushrooms, spinach, green beans etc but put in raw sliced tomato, grated cheese, do as you see fit yk. Then pop in the oven until the egg raises and firms up.
