Oven: preheat your oven to 180°C / 350-375°F / Gas Mark 4-5.
Green onions: add the chopped segments of green onions to the food processor and blitz till they are chopped into fine pieces.
Tart filling: then add the cream cheese, crab meat, parmesan cheese, mustard, Worcestershire sauce, salt and pepper. Blitz till combined then transfer to medium sized mixing bowl.
Tart shells: use a clean dry chopping board and a 6.5cm (2.5 inch) pastry cutter to cut a round circle with fluted perimeter from each slice of bread.
Corn: add the corn kernels to the tart filling and use a spatula to stir and gently fold the kernels into the mixture.
Patty pan: grease 2 12 hole patty pans or tart pans with cooking spray. Then working one at a time push the bread rounds into the patty pan so that they stick to the oil and form the tartlet shells.
Fill: working with 2 teapoons (1 in each hand) spoon a heaped teaspoon of the tart filling into each of the tart shells. Repeat to fill all of the tarts.
Oven bake: place the patty pans into the oven and let the tarts cook for 10 till 12 minutes. Once cooked, use a pair of oven mitts to remove the patty pans and place them onto a wire cooling rack.
To serve: use a teaspoon to gently push the tarts of out the pan. Plate with and garnish with some freshly chopped chives. Provide a small bowl of sweet chilli sauce and serve warm.
