Peel and chop potatoes in big chunks. Boil until a fork pokes through the potato easily. You don't want to boil the potatoes so much that the potato falls apart when poking. You want the potato to keep it's shape and be somewhat firm, but not too soft. 

Peel and chop carrots. Boil until ready in a separate pan. 

Shuck peas and boil if desired. I don't boil because I like the fresh peas to be crisp. 

If using other vegetables, like beans. Clean, cut, and prepare accordingly. As the vegetables are boiling, start preparing the sauce. 

To make the sauce, heat the butter in a large sauce pan on low heat until melted. Stir in flour, salt, and pepper. Cook over low heat, stirring constantly, until the mix is smooth and bubbly; remove from heat. Stir in milk. Return to heat until boiling, stirring constantly. Boil and stir for one more minute.

Once the sauce is ready, stir in the prepared vegetables. 

NOTE: You will have to eyeball the number of vegetables for the portion of sauce you are making. Add vegetables, then mix in. Repeat until you have plenty of vegetables in the pot, but not too many. You want the Vegan Farmer's Delight to be very creamy!
