Frozen and canned ones. And the tubs of greens in the fresh vegetables section.

For instance, according to the labels of these items I have, per serving:
Frozen peas: Has no vitamins, 2% calcium, 6% iron, 2% potassium.
Frozen corn: Has no vitamins, 2% calcium, 0% iron, 4% potassium.
Canned corn: Has no vitamins, 0% calcium, 2% iron, 2% potassium.
Canned pineapple: Has no vitamins, 2% calcium, 0% iron, 4% potassium.
Canned pears: Has no vitamins, 2% calcium, 0% iron, 2% potassium.
Canned pasta sauce: Has no vitamins, 0% calcium, 6% iron, 6% potassium.

Canned spinach (Delhi Saag) - this one still has the old-style label:
has 90% Vit A, 0% Vit C, 8% calcium, 6% iron.
This one sounds much healthier than the rest because of that 90% Vit A, even though for all I know some of the others may be high in Vit A or C or other vitamins too, but they aren't listed.

Peanut Butter - they opted to include some non-required vitamins on this one and it therefore sounds much healthier to me than the above fruits and vegetables, except the spinach:
has 0% Vit D, 2% calcium, 6% iron, 4% potassium, 15% Vit E, 35% Niacin.

Dry-roasted Peanuts - ditto:
has 0% Vit D, 0% calcium, 2% iron, 4% potassium, 10% Vit E, 20% Niacin, 10% magnesium, 10% copper, 20% manganese.

Based on that, the peanuts sound the healthiest! They're high in fiber and low in sugar too.
