There are many different ways to make a Margarita Pie, but the basic ingredients are usually a graham cracker or cookie crust, sweetened condensed milk, lime juice, tequila, and triple sec. Sometimes other ingredients like sour cream, whipped cream, or fruit are added as well.
Melt margarine in a small saucepan. Stir in pretzel crumbs and sugar. Mix well.
Press crumbs on bottom and sides of a buttered 9 inch pie pan and chill.
In large bowl combine milk, lime juice, tequilla, and Triple Sec. Mix well. Fold in whipped cream. Pour into prepared crust.
Freeze or chill until firm for 2 hours in freezer or 4 hours in fridge. Refrigerate or freeze leftovers( if there are any)!
