1. Mix all the dry ingredients in a large bowl. This mixes easily by hand and will probably make a big purple mess if you use a mixer.
2. Add milk and olive oil; mix until a thick batter forms. This batter may be too thick based on the amount of seasoning you add, so additional milk may be needed. Try not to thin the batter out too much or it may not stick as well.
3. Heat oil to 375 degrees F. I use a deep fryer on my back porch to prevent the oil from greasing up the kitchen and house.
4. Pour vegetables into the batter. Stir batter over veggies until they all have a nice coating. Deep fry in small batches for about 4 minutes per batch.
