Not knowing your "suburban prepping" circumstance, nor space available, you might consider container gardening on a porch or balcony.
Also, if a conventional garden area, there are motion activated water sprinklers to keep out pests (both four legged, and two legged pests).
Another alternative is to interplant veggies along with flowering plants.
Another alternative is to plant camouflaged vegetables like purple carrots, black krim tomatoes, etc., and other heirloom varieties with unusual coloring.
Also, there are several misplaced edible plants (we call them weeds) such as purslane, dandelion greens, burdock, sunchokes,
egyption walking onions, wild chive, spearmint, water cress, etc.
Euell Gibbons wrote a whole series of books, starting with "Stalking the Wild Asperigas" for finding edible wild plants in nature, and describes where to find for them.

Thanks to you both. I have some raised beds I have built and used in recent years, because some heavy metals came back in my soil tests.
Would be a shame to have others do my harvesting for me if the going got tough, however. Haven’t grown them, but I love Jerusalem artichokes!

Lol, I love the name. I’ve read that the younger leaves on Kudzu are edible, more like a salad green.
