For vegetarian dishes it’s helpful to look at non European cuisines. Curries and soups both have a huge variety and don’t require a meat to be complete. Chickpeas also make a great protein substitute besides Tofu. Dumplings are other meat free food that are pretty good, but they tend to be carb and oil heavy so not necessarily healthy. Indian and Thai both have great vegetarian dishes that aren’t meat based dishes with the meat removed.

Finally, cooking with spices makes vegetables much more varied. Americans seem to think spices and rubs are only for meat and vegetables need to be plain. A well spiced vegetable dish is delicious.
