Preheat the waffle iron on medium heat.
Bring water to a boil in a smaller pot with the vingear (if using).
Grate the sweet potatoes and halloumi, add to a bowl.
Add oat flour, milk and yogurt. Stir to combine.
Grease the waffle iron with some olive oil.
I cook one egg at a time. Start by cracking one egg into a small bowl.
When the water starts to boil, lower the heat and wait until the water just simmers.
Using a whisk or a wooden spoon create a swirl in the water.
Gently slip the egg into the simmering water. Let it cook for 2-3 minutes, depending on how runny you prefer your eggs.
Remove the egg with slotted spoon and drain well.
Repeat with the remaining egg.
Place the waffles on two plates. Top with spinach, sliced avocado and poached eggs. Ground fresh black pepper over it and serve immediately.
