I do not know your flora, but it seems Capsella bursa-pastoris, from Brassicaceae (cabbage/mustard family). Note: there can be more similar species in your region, but usually similar.
You may recognize it with heart-shaped fruits. Note: heart has not the heart-shape, so in past they say it has shape of a shepherd bag (or better flask). You may see many of these plants (and in general of Brassicaceae) in spring.
As you see in Wikipedia (but I got this also independently), you may eat the rosettes. Just this plant is ruderal (as many chicories), and so please consider the soil: it could be contaminated (e.g. if you harvest near roads).
Just a warning: please do no eat plant you do not know: there are many toxic plants (which may seems the normal plants), some are really deadly toxic (see the many deaths which confused Colchicum autumnale as Allium ursinum), or many plants which are toxic if ate on large quantities (but nice to enhance a salad).
