  A superconductor with $p_x+ip_y$ order has long fascinated the physics
community because vortex defects in such a system host Majorana zero modes.
Here we propose a simple construction of a chiral superconductor using
proximitized quantum wires and twist angle engineering as basic ingredients. We
show that a weakly coupled parallel array of such wires forms a gapless
$p$-wave superconductor. Two such arrays, stacked on top of one another with a
twist angle close to $90^\circ$, spontaneously break time reversal symmetry and
form a robust, fully gapped $p_x+ip_y$ superconductor. We map out topological
phases of the proposed system, demonstrate existence of Majorana zero modes in
vortices, and discuss prospects for experimental realization.
