Start by preparing crumble topping. Put flour, sugar and cubed, cold vegan butter in a large bowl and start working the butter into the mixture with your fingers, squashing it gently as you go until more or less incorporated and you get that breadcrumbs like consistency. This part can be also done in a food processor.
Next add oats, ground almonds, chopped walnuts and sunflower seeds and incorporate them into the crumble by mixing in with your hand. Once crumble is ready set it aside and get on with preparing spiced pears.
Preheat the oven to 180C/350F/Gas Mark 4.
Peel, core and slice the pears. If your pears are a bit overripe and falling apart a bit, don't worry about slicing them but cut them into chunks which will be fine as well.
Melt some vegan butter in a pan or ovenproof skillet. Add pears followed by spices and sugar, give it all a gentle mix.
Gently fry the pears until sugar has dissolved and pears softened a bit (5-10 min). The timing will depend on your pears and whether they were quite firm or a bit overripe.
Transfer your pear mixture into lightly buttered pie/crumble dish and top it with crumble topping.
Bake in preheated oven for 25-30 minutes until the crumble is nice and golden and pear mixture is bubbling.
Serve and enjoy!
