Most of the non-Abelian string vortices studied so far are characterized by two-dimensional CP(N) models with various degrees of supersymmetry on their worldsheet. We generalize this construction to "composite"non-Abelian strings supporting the Grassmann G(L,M) models (here L+M=N). The generalization is straightforward and provides, among other results, a simple and transparent way for counting the number of vacua in N=(2,2) Grassmannian model.
