Melt your chocolate in the microwave using the 50% power setting and stirring at 30 second intervals. Stir the olive oil into the melted chocolate. Pour the mixture onto two plates lined with parchment paper or non-stick foil. Put plates of melted chocolate in the freezer for about 30 minutes or until solid.
In a large mixing bowl, stir together your condensed milk, half & half, salt and flavorings. Add a little blue and yellow to make green, or just add a little green coloring if you have that.
In a second bowl, whip the cream until stiff peaks form. Fold the whipped cream into the condensed milk mixture.Now take your chocolate out of the freezer, peel away the foil and cut the chocolate into chunks. Stir the chunks into the ice cream. Divide equally among two small plastic containers or pour into a loaf pan and cover with foil. Freeze overnight. Makes about 6 to 8 servings. It's rich so you might want to portion it out among small, pretty, glasses.
