I'm all for living in a "lazy lima bean" mode yet still shudder at the thought of throwing food and money away; my ancestors would be proud so me;).
OK, RedCatcher.....how about buying a powdered pancake mix that you only need to add water and place in empty disposable water bottle?
When you want to eat pancakes add the water, "shake + pour". Without knowing how many pancakes constitutes a serving for you, I'd say a 16 -25 fl oz bottle would do fine for 2 people giving you enough head space to shake with ease. You'll do best with a wide mouth bottle.
