In a small bowl, mix 2 tablespoons of flax seeds with lemon zest and juice. Let sit for at least 5 minutes (This makes lemony flax “egg” goo).
In a large bowl, mix together Greek yogurt, brown sugar, milk, vanilla, poppy seeds, and flax “egg” goo.
In a separate bowl, whisk together all of the dry ingredients - flour, salt, baking soda, baking powder. Once well combined, stir in (dry) TVP very well.
Add dry ingredients slowly to wet ingredients and combine.
Evenly distribute the batter across all 12 (lined) muffin cup things on your muffin tray.
Bake for 15 - 17 minutes. Will come out a little gooey (if you cook too long it will dry out); let sit for about 15 - 30 minutes and they will set up.
