Trying to make a segment of code more efficient in a function

Is there a more efficient way to check if what the user has entered (“food_ordered”) is on the “order_menu” without having to use “food_keys” or “food_names”?

order_menu = {("C", "Chips (Scoops)") : 2.80, ("F", "Fish (Battered)") : 2.90, ("Fc", "Fish (Crumbed)") : 4.90, ("Fib", "Filet (Battered)") : 6.90, ("Fic", "Filet (Crumbed)") : 6.90, 
         ("Hd", "Hot Dog") : 2.60, ("S", "Sausage") : 2.60, ("Mp" , "Meat Patty (Homemade)") : 3.90, ("Cr", "Crabstick") : 2.50, ("Sr", "Spring Roll (Homemade)") : 2.80, 
         ("Cr", "Curry Roll (Homemade)"): 2.80, ("Pof", "Potato Fritter (Homemade)") : 1.20, ("Paf", "Paua Fritter (Homemade)") : 5.90, ("Cn", "Chicken Nugget") : 1, 
         ("Mh", "Mini Hot Dog (On a stick)") : 1.20, ("Pf", "Pineapple Fritter") : 2.50}
order_dictionary = {}

food_keys = []
food_names = []
for (food_key, food_name), price in order_menu.items():
    food_keys.append(food_key)
    food_names.append(food_name)

    
def order():
    for food_name, price in order_menu.items():
        print(f"• {food_name[1]:<35} {'('+ food_name[0] + ')': <10} ${price:.2f} each")    
    while True:
        food_ordered = input("Order: (Type 'End' when you have finished) ").title()
        if food_ordered == "End" and len(order_dictionary) > 0:
            break
        elif food_ordered in food_keys or food_ordered in food_names:
            for (key, food_name), price in order_menu.items():
                if food_ordered == key:
                    food_ordered = food_name 
            while True:
                try:
                    quantity_food = int(input("Number of {}: ".format(food_ordered)))
                    break
                except ValueError:
                    print("Please input NUMBERS only.")                
            if quantity_food > 10:
                quantity_food_check = int(input("Are you sure you want x{} {}? (re-enter to confirm): ".format(quantity_food, food_ordered)))
                order_dictionary[food_ordered] = quantity_food
            else:
                order_dictionary[food_ordered] = quantity_food
        else:
            print("Please enter an actual item on the menu!")    

order()
   

I don’t see a way to do that, given your data structure, but with a different data structure, you could do something such as this proof of concept:

menu_list = [
    ("Chips (Scoops)", 2.80),
    ("Fish (Battered)", 2.90),
    ("Fish (Crumbed)", 4.90)
    ]

print("=============Menu=============")

for menu, items in enumerate(menu_list, 1):
    print(f"{menu}: ",end='')
    for item in items:
        if type(item) == float:
            print (f"${item:2.2f}",end='')
        else:
            print(f"{item}\t",end='')
    print()

print()

item = 0
while not item or item > len(menu_list):
    try:
        item = int(input("Please choose from the menu: "))
    except ValueError:
        item = 0

ordered_item = int(item)-1

print(f"\nOrdered item: {menu_list[ordered_item]}")

code edit: update to handle ValueError and simplify the while condition.
