I was vegan for about 4 years, and learned that the way you cook something goes a long way towards how much variety you can get from such a small selection of foods. Spices help immensely, so work on your spice cabinet and don't be afraid of salt. Learning to make different kinds of sauces and dressings also will be a good thing to have in your toolbox.
Technically eggs aren't vegan, but start where you can. It's actually cool that you're including eggs in your diet because there's a ton you can do with eggs. Will definitely help to learn different egg recipes so you don't get tired of the same foods.
Certain veggies are tough and can take a while to roast in the oven, and pretty much every other veggie needs to be chopped before consuming, so meal prep helped me a lot. Setting up time to slice and dice and store away all the veggies I bought went a long way towards making cooking easier.
There might be vegan alternatives to meat, cheese, and dairy that have massively improved in quality over the years, so you might want to include them if you can. A sweet little vegan dessert every once in a while will be a nice reward for your efforts.
Just don't feel like you're punishing yourself or view it as a chore, because there really is a ton of variety with vegan foods.
