4.Slice 3/4 -inch steaks through one half. Repeat for other side. You should get 3 to 4 steaks.

6. In medium bowl: mix 3/4 cups flour, 1 tbsp cornstarch, 1 tsp smoked paprika, 1/2 tsp garlic powder, 1/2 tsp onion powder, 1/2 teaspoon fine grind black pepper, 3/4 tsp salt (or to taste). Transfer to a small rimmed baking sheet/dish. 6. Add 3/4 cup non-dairy milk to small rimmed dish. 
7. Dip both sides cauliflower steaks into milk. Use spoon to get into cracks and tops.
8. Dip into flour mixture until fully coated on both sides, using a spoon to place flour into cracks. Shake to remove excess.
