There are two schools of thought...

The ride-breakfast/meal-ride approach is fine for casual riding with family or non-cycling friends. That way, the meal is the enticement to get them out on their bikes. I'll do that for the company, and to be an encouragement to the others to remain/become active. The point is the comraderie foremost.

The other approach, which I take with buddies who ride, is to only snack or eat enough to maintain riding energy. Maybe a stop at a distant supermarket to pick up some fig bars or a sandwhich, and then onward. I typically carry enough food/snacks for four or five hours on the bike. More, and I'll have to stop to get something. The point is riding first, and then socializing second.

Both are fine. I lean more toward number two rather than number one. My hope is to drag everyone eventually into number two...
