1 head of cauliflower, cut into small pieces
1 summer squash (yellow zucchini), cut into a large dice
1 yellow onion, sliced
salt and pepper
roll of tin foil
Prepare fire by allowing to to burn down to coals.
On the picnic table, lay out 4 squares of heavy-duty aluminum foil, about one foot square, and oil lightly.
In the center of each piece of foil, up the cauliflower, squash and onion. Season with salt and pepper and drizzle with olive oil.
Bring opposite corners of foil together and seal. Fold over the seam and seal tightly to make a secure package.
Place on coals (a little flame is fine) and roast, turning occasionally, for about 45 minutes. Check to make sure vegetables are cooked through. Serve.
NOTE: Just before serving, I like to add a little bit CheezWiz or a cheese slice to each packet.
