It is already a task if you are on a strict vigil of a gluten-free diet. Being a vegetarian and gluten sensitive can make things difficult as you are left with very limited options to mix and match ingredients.
There are still some recipe ideas that you can use to cook for dinner and make it less punishing and more savory.

If you are a vegetarian and still wish to have a complete four-course meal for your dinner, then you can start with a simple broccoli soup.

Boil mash small pieces of broccoli and mix water for a soupy consistency, add salt. You may add sugar to give a sweet twist (and balance the acidity at the same time), and black pepper. Stir boil it for under two minutes on a slow flame. Add cream and (boiled) corn kernels. The grainy texture and the sweet-salty flavor of the soup with an after-kick of smoky black pepper assisted with the occasional bites into corn kernels will make you fall in love with this soup.

For appetizers, you can use the popular combination of potato and cheese. Rather than having plain old potato cheesy fries, cut potatoes into equal halves. With their jackets still on, scoop out a portion of it and add a mixture of sour cream and Parmesan cheese to the potatoes. Glaze them with butter and bake them golden brown. Once out of the oven, garnish them with seasoning of your choice (maybe oregano or simply black pepper).

The main course leaves you with pretty less options and substituting meat from the traditional dish is not a good idea. Fret not, you still can have a filling main course meal. A simple serving of black kidney beans pressure cooked in rich tomato and onion gravy served with rice of your choice is a healthy alternative which is gluten-free. Kidney beans are a good source of proteins and healthy vitamins while rice is rich in carbohydrates. The fibrous content that gluten rich wheat was supposed to provide is taken care by kidney beans, though gluten-free they are rich source of dietary fiber.

Fancy a chocolate mousse cake? Well, the traditional mousse cake has flour as an ingredient which is loaded with gluten. A simple 4 ingredients chocolate mousse cake is sure to take care of your post meal cravings for desserts. The best thing about this chocolate mousse cake is, that it is flour-free hence gluten-free. Whisk four eggs until they appear white and frothy. Add sugar while whisking. When the whisked eggs look nearly white, add them to already (butter added) cooled melted dark chocolate. Have a light hand while folding those eggs into the chocolate. Pour mixture into a pan. Bake for five minutes, then turn down to 350°F/180°C and bake for another 25-30 minutes. Put a toothpick in the cake and remove it, your chocolate mousse cake is ready to serve, if it comes without the slightest trace of chocolate.
