I agree on Youtube being good for inspiration if you're looking for "Full Day of Eating" type inspo. Just search for Full Day of Eating Vegan or plantbased and lots of people will have videos where they show a full day worth of meals. Niomi Smart is one of them and she also has a cookbook if you want to order that.
If you're also looking for just general meal inspiration there is always Pinterest.
I'm not the type of person that gets bored easily when it comes to food - I like a variety of things and I'm not a picky eater at all, but if I find something I really like I can still easily get stuck on it and have it every day for weeks... so a typical day for me can look like this; porridge (oatmeal) with raspberries, blueberries, mangos, chia seeds, chopped up almonds and cashews (or peanut butter if I'm feeling lazy) for breakfast, then maybe a big veggie wok for lunch and nachos, guacamole, mixed salad, fruit and chickpea chili for dinner. I don't snack a lot - I don't find that I need to really, but when I do I snack on berries, sliced apple with ground cinnamon or peanut/almond butter, pumpkin seeds or chopped up bell peppers.
