Side and salad to go with pumpkin lasagna?

I am making a brussels sprouts slaw for our family's traditional turkey dinner that I think would be a terrific side for your lasagna. It has thin-sliced brussels sprouts, chopped dates and hazelnuts, and a cider vinegar dressing. Could easily be adapted to other ingredients. http://www.feastingathome.com/brussel-sprouts-slaw-with-hazelnuts-and-dates/

Appetizer - small bites of something wìth a sharp or slightly bitter edge...maybe eggplant, endive, olive or artichoke (little or no bread bc the main dish is strong on grain).
Salad - something in the French style, served after the main, as a palate cleanser and transition to coffee or dessert. Watercress or arugula with oranges and onions in a classic vinaigrette.

Lots of good suggestions below...what I want to know is: where can I find your pumpkin lasagna recipe? It sounds delicious! :-)

I'd either go super simple - maybe blanched green bean salad and a fresh green salad with minimal toppings, maybe sliced almonds?

Or go Italian and make a brussels sprouts caesar? Great recipe here on Food52. https://food52.com/recipes/39327-brussels-sprouts-caesar

Agree, you don't need much! Some ideas for light things to cut the richness:
