Fudge-Filled Bars

2 cups quick cooking oats
1 1/2 cups all-purpose flour
1 cup packed brown sugar
3/4 teaspoon salt
1 cup butter or margarine, melted
1 cup chopped pecans
1 (14 ounce) can sweetened condensed milk
6 ounces semisweet chocolate chips
2 tablespoons shortening
1 cup plain M&M's

In a bowl combine oats, flour, brown sugar and salt. Add butter and mix until crumbly. Stir in pecans. Set aside 1 1/2 cup for topping. Press remaining crumb mixture into a greased 9 x 13-inch pan.

In a saucepan, combine milk, chocolate chips and shortening; cook and stir over low heat until chips are melted. Spread over crust; sprinkle with reserved crumb mixture. Top with M&M's. Bake at 350 degrees F for 20 to 25 minutes or until edges are golden brown.
