Linda Wernli's BIG PAN Brownies

(Used this for Girls' Camp 2012 - it makes a HUGE pan of brownies, like 60 or 80 squares! Linda has the pan. Thanks, Linda!)

2 3/4 cups shortening
5 squares unsweetened chocolate  (I just convert this to cocoa & shortening)
5 1/2 cups sugar
12 eggs
3/4 tsp. salt (cut down)
1 1/2 Tbsp. vanilla
5 cups flour (heaping)
2 1/2 cups chopped nuts (optional)

Melt shortening and chocolate together. Mix sugar, eggs, salt, and vanilla
in a mixing bowl. Add shortening and chocolate mixture and mix. Add flour
and nuts, mix together for a couple of minutes. Pour into a greased and
floured pan. Bake at 350 for approx. 30 minutes.
