Online grocery shopping is declining although it’s still at higher numbers than before the pandemic. It’s hard to find new products online. You get tired pretty quickly of just browsing through item after item you could care less about. I think a lot of us want to see things in person. I buy a lot of fruits and vegetables and while I’ve had pretty good luck in the past about getting produce from grocery stores that deliver that was nice, I still prefer to see it and choose it at the store.
Maybe look up some recipes for specific foods you enjoy. Along the lines of say you like soup, creamy soups. A variety will come up. Pick one that requires a new ingredient. Creamy carrot cashew bisque soup. Carrots, cashews, ginger, garlic and olive oil Coconut oil or coconut milk can be used too. Cashews make an excellent creamy base. You soak or boil them, then blend.
Marinated seitan or toasted nutritional yeast coated tofu. Great to snack on. Looking at some recipes might help give you some ideas to branch out and try some different ingredients. When I turned vegetarian at age 11, I made a vegetarian dinner every Sunday from a gourmet vegetarian recipe book I had found for my whole family. Some turned out great, some were just okay but I think we all enjoyed trying some different things.
This is a website I love as she does wonderful recipes, but there are plenty that will come up in search obviously!
