With 6-8 pounds of spaghetti and 6 jars of PB, you can make whole boatloads of noodles with peanut sauce. Yummers! And it's a great recipe for summer and for bad cooks, since the only cooking is boiling the spaghetti.
3 T peanut butter
6 T hoisin sauce (you can get huge bottles cheap at Asian groceries)
3 T white vinegar
1/4 cup no-chicken broth, vegetable broth, or water
1 T sugar
1-2 t Chinese style hot chili sauce (sub Tabasco if that's what you have)
Stir together the peanut butter and hoisin sauce in a small bowl until smooth. Add the vinegar and chili sauce a little at a time, tasting until you like the flavor. Then thin with broth/water, again adding a little at a time, until you are happy with the consistency. Everyone's peanut sauce is different! Add the sugar (or more hoisin) if you still want it sweeter. If you use water, you may want to add a little soy sauce for saltiness.
Peanut sauce =
You can make a pretty good size batch of peanut sauce and keep it in the fridge if you want. Once you have peanut sauce made, just boil spaghetti, rinse and chill, then add peanut sauce and any combination of the following cut-up fresh veggies: carrots, cucumbers, green onions, bean sprouts, bell peppers, sugar snap peas, snow peas, asparagus. You can also dress it up with chopped fresh herbs including basil, mint, chives, or cilantro if you can get your hands on them.
Another really cheap food (in many places, not all) that goes great with PB is bananas. Slap some PB and a quartered banana on a piece of bread and you've got a quick, easy, and delicious breakfast.
PS: I personally think some of the best ways to jumpstart your nutrition are sunflower seeds, pumpkin seeds, sesame seeds, and flax seeds. While it's expensive to buy a pound of them, they last a long time in an airtight container in your freezer, and they're loaded with minerals and healthy fats that are vital to your long-term health. The most economical way to buy them is probably in bulk from a natural food store or grocery store. Try roasting them and mixing them into granola or trail mix. Just don't roast flax seeds-- heat destroys the delicate omega-3 fatty acids that make them so healthful.

recipe for an incredibly healthy snack. Feel free to skip the more expensive nuts. I personally don't think it needs all those nuts anyway-- they tip it way towards the fatty end of the scale. Frankly, I'd omit all the nuts and coconut and just focus on the seeds. Just add the flax seeds after baking instead of before like it says.
