Grindaddy's Green Onion Chip Dip

This is the original, which was not really a recipe actually.. but we made him do it slowly a couple of years ago, and reverse engineered this:

1 pack (8 oz) cream cheese
1 1/2 T lemon juice
3.5 T milk
2 T green onions, cut lengthwise (1 bunch)
1/4 t salt

But everyone is now avoiding dairy, even Grindaddy. So, this year, we are trying the Vegan version of this. But Grammy wanted to use Baked Lay's. I draw the line somewhere. I went to CVS and got some real potato chips!
