In Doy’s garden

Log it in Doydum and a row of tomatoes sprouts in today’s bed in front of Doy’s house.

Tuna packed in water or brine and drained, a pantry staple for quick salads, sandwiches, pasta and wraps. These numbers are for the drained fish, which is very lean and mostly protein.

Tuna in oil carries much more fat even after draining, so check which one your can says.
