$20 Dollar Tree Halloween Dinner!

Today I set out to make a $20 halloween dinner for 4, complete with an appetizer, entree, dessert, and a beverage. The only caveat, my Dollar Tree doesn't have a working fridge and their freezer is practically empty. But we still made some magic happen!
The meals:
Appetizer: "Mummified" Tamale Pie
Biscuit Mix
Canned Tamales
Canned chili
I mixed the biscuit mix with 1/4 cup of water and kneaded it together like a pie dough. Cover and chill for 30 minutes, roll it out as thin as possible and cut it into thin strips.
Open chili and pour into the bottom of a baking dish, add tamales (remove paper first) then lay down your biscuit strips in a "mummy" style. Bake at 350 for 25 minutes.
Entree: Spider Pizza Pasta
2 boxes of macaroni & cheese
Pasta sauce
Pepperoni
Black Olives
Parmesan cheese
Add the macaroni noodles into a pot with 3 cups of water, 1 cup of pasta sauce, 2 tablespoons of oil, and the cheese powder packets. Mix to combine then bring to a boil and simmer for 6 to 8 minutes until the pasta is cooked. Top with parmesan cheese, pepperoni, and black olive spiders.
Dessert: Vampire Mouth Cookies
Chocolate Chip Cookies
Red Frosting
Mini Marshmallows
Gently cut cookies in half (use a sawing motion so cookies don't break). Spread the inside of each half with some red frosting and a few mini marshmallow "teeth". Add 2nd cookie half on top to complete the mouth.
Bonus:
Juice & Gummy worms for a "pickled worm" punch
Bugles, caramel popcorn and optional candy corn for a sweet and salty movie mix
Enjoy!
