Sharp, flavorful cheeses are really good on Ryvita. You can slice them very thin (I actually use a vegetable peeler for hard cheeses) or spread them thin if they are soft, and save the calories. Sharp cheddar, parmesan or goat cheeses are usually what I use, and they're very decorative when you top the cheese with a contrasting vegetable or fruit -- things like halved grapes, thin slices of pear, sun-dried tomatoes. Makes it all fancy-like, as if you're having a party. There are so many nice English cheeses, and they tend to be more flavorful than the processed cheeses which are common in the US. Although sometimes a bit of Velveeta on top is good too.
Hardboiled eggs, deviled or sliced, then topped with chopped herbs or rocket (arugula) or sundried tomato or olives.
Flavored cream cheese, like strawberry or garlic-herb or whatever, is also really good with them. Peanut butter was an old standby in my household when I was small, but that not may be your taste.
I also really like tuna, pickled herring, or sardines on Ryvita. Again, fishy may be an acquired taste for you. I have a thing for sardines in tomato sauce, which are very inexpensive here, and a good source of protein and Omega 3s. And sometimes they just hit the spot. In the case of the sardines the Ryvita is really just a delivery system that seems a bit more civilized than eating them out of the can. They have the John West brand here which has all sorts of variations in the sardine-kipper family whose details I'm not familiar with (silts?!?) but are all good.
You could try googling Ryvita toppings for ideas, or also look up recipes for tea sandwich fillings since they are traditionally on rather bland breads also.
