Hi Robbie,
Roll the noodles with the fillings, change any/all ingredients, or use vegie slices to replace the pasta. Maybe grill the vegies first.
It seems that a lot of people are calling things Lasagna, that do not use Lasagna noodles. Any noodle can substitute
White Sauces, Red sauces. Try Cajun/Tex Mex/Greek/French/Polish/Asian, etc. seasonings and flavors.
Look at the ingredients that you have, put the flavors and textures together in your mind, make something.
Olives aren't usually in one, but if you think it would taste good... Too many options...
Hope you think of something you like.
