My go to dinner party foods are fajitas (with chips guacamole and margaritas)and shish kebobs on the grill. I find for even fussy, picky, vegan, vegetarian, allergic people - these dinners seem to work.
My other tips are a make way ahead dessert. I like to do ice cream pies. They can be done days or even a week ahead.
I also like to do heavier before dinner snacks. The cocktail hour is often peoples favorite part. I always do some cheese, crackers, veggies dips and some sort of bruschetta.
I always have beer, wine (red and white), soft drinks and some signature cocktail.
I love to entertain and seem to throw a dinner party every couple of weeks.
