Not an expert cook or anything but will throw some ideas.
You can do some mean desserts using fruit a microwave and some mead. You know the recipe wine-poached pears? very easy with mead. Also you can substitute pears with apples or do baked apples (I dont know how its called in english, sorry, im spanish) which is a recipe where you just take out the apples heart and put them in the oven with some whiskey/bourbon/coentrau and some sugar and cook them. Just substitute the liquor with mead, preferably a spiced one maybe a cinnamon one.
Apart from that, you mainly substitute wine for mead yes. You can use it in stews or stuff like that
You can also use honey and just to list some recipes the fried apples with honey (this is found in chinese restaurants mostly) or basically anything that uses french sauce (honey-mustard at a ratio between 1-1 to 1-2). I use it to do some nice burritos with some chicken and slow-fried onion, but i have seen it with french omelette in sandwiches and in other places. Honey and onions are always a win.
Think about different styles of mead. sweet vanilla or cinnamon (or even marshmallow if you ever done that, its delicious) mead can go great with desserts while some braggot/raisin or prune dry-ish melomel can go great with meat stews. Dry trads can go better with some other stuff such as any nearly dish with mushrooms or anywhere you would use white wine. And bochets can have a place too somewhere.
Edit: PS; The french sauce burrito is highly adaptable, you can change the chicken for pork or lamb and its usually a hit whenever and wherever i do it. If you are interested in a full recipe i can write it. Its also really simple and fast. But i dont know what type of foods you will be serving. You can substitute the burrito for a sandwich or any other bread. The desserts are usually done by other people with my mead but i can get you a full detailed recipe too if you want it. Altough those can be easily found in the internet i believe
