Preheat oven to 170 degrees fan forced
Butter a large baking dish (I used 20cm x 32cm)
Place torn spinach leave on bottom of dish
Place meat into TM bowl and chop 3 seconds / speed 5, scatter over spinach leaves
Place cheese into TM bowl and chop 4 seconds / speed 8, scatter over meat
Scatter over the spring onions, and then the frozen peas
Put custard ingredients into TM bowl and mix 10 seconds / reverse / speed 4
Pour the custard over the other ingredients in the baking dish
Top with the tomatoes and parsley (if using)
Bake for 1 hour and 15 minutes (baking time will depend on the depth of your dish and the fillings you use ... test by pressing the middle of the custard, if it still feels a touch soft then bake for a further 5 to 10 minutes)
Remove from oven and allow to rest for 15 minutes before cutting
