It can be expensive to buy a good cheap mix of seeds to sprinkle on breakfasts, salads and desserts, so I make my own. I buy large good value bags of pumpkin seeds, sesame seeds, sunflower seeds and linseed and put them in a jar:
You can vary the quantities according to how many of each seed you prefer. Then I simply shake them up before use to get an even amount of each to use.
The smaller seeds tend to work their way to the bottom of the jar so I shake before every use.
