Salsa nuts - you can buy them at grocery stores. Look for little green bags. They remind me a bit of those Boston Baked Beans/Nuts, that have that red, candied shell. But these peanuts have a tasty "salsa" flavoured shell that, although it may not be that incredible upon first taste, make you want to keep eating them. 2 points out of 5 on a scale of EVIL.
Randomly shaped Ritz-like crackers - I've only found them at Rimi, haven't checked Stockman, but know that Nelda does not carry them. These crackers come in all kinds of shapes, have the right amount of salt, and for 0.35 LVL a bag are not something you should think twice about buying. 4 EVIL points. (Note: stay away from the goldfish-shaped crackers if you don't like deceitful foods. The "goldfish" are sweetened crackers with no salt and little to no fun-factor.)
Sweet cottage cheese sticks (Saldie biezpiena stienisi) - a snack I just discovered, made and sold by Index Cafe. Baked, little stick-treats that seem to be nothing more than a more-baked, little stick-treat version of "Latvian cheesecake". They cost 0.85 LVL a pack and go great with coffee. Another reason to love Index Cafe, if more were ever needed. 2 out of 5 EVIL points.
Cheese balls (Siera bumbinas) - Can be found in any grocery store; just make sure you buy the Latvian-made Adazi brand. They're the best. Even better than North American Cheetos. For real. Do not buy these if you have food-guilt issues. If I let loose, I can clear one medium bag by myself over the course of an evening - I now buy them very rarely (once a month tops), because I am aware of the dangers. 5 out of 5 EVIL points.
Dried hibiscus - slightly scary looking, but with a very mild taste. The first time I had one of these was at a relative's house. The next time I saw them was at the Riga Central Market, among the counters of other dried goods. Dried hibiscus is tasty, unobtrusive in flavour, and probably has some kind of health benefit. They also keep forever (at least mine have). And yes, I had to add these to balance out the preceding list of junk-type-foods. 3 out of 5 EVIL points.
This list will be continued as necessary.
