Let X be an m-dimensional variety in the d-dimensional complex projective space P^d. Let k be a positive integer such that the combinatorial number "m+k choosing k" is smaller than or equal to d. Consider the following interpolation problem: does there exist a variety Y in P^d of dimension strictly smaller than "m+k choosing k", with X in Y, such that the tangent space to Y at a point p in X is equal to the k-th osculating space to X at p, for almost all points p in X? In this paper we consider this question in the toric setting. We prove that if X is toric, then there is a unique toric variety Y solving the above interpolation problem. We identify Y in the general case and we explicitly compute some of its invariants when X is a toric curve.
