5 frugal food things to be specific
1. I found a dog gate in a FREE pile. Although it is in its original box, the gate was smashed to pieces. (They must have had a very powerful dog) I did salvage 2 metal grids I plan to use as a pea trellis next spring. (too late for this years crop)
2.My friend Kira came back from a camping trip and gave me two trout. DELICIOUS!
3.My sister volunteered at a food stop for a bike race and came back with grapes and bananas. I ate the grapes and froze the bananas for banana bread and or smoothies.
4.I picked up a perfectly good onion off the street.
5. I made my own BBQ sauce. I reused my empty BBQ bottle to store it.
Do you have any Frugal things you want to boast about?

Cannot offer anything except did not throw away any food, which is unusual on trash night. Loved the onion on the street. I would do the same!
I do have a frugal thing: making crumbs. Someone opened two packs of savory crackers. The humidity did the rest. I crushed them to top a future casserole. Two opened boxes of not so good cereal. Crushed with some brown sugar added for a future fruit crisp. Does that count as two?
I love your idea for crisp topping. good job!
