The amount of processed soy you have to eat to have any detrimental effect is massive.

We eat it probably once a week, tempeh probably once a fortnight.

My favourite way to eat firm tofu is baked with a mix of hoi sin sauce, soy sauce and golden syrup.
My favourite way to eat silken tofu is raw, blended with beetroot, garlic and cashews as a delicious dip
My favourite way to eat tempeh is roasted with root vegies.

Think about not seeking to replace meat, but cook meals that don't have it. Much more delicious.
