There's at least the Gelada: "Why These Vegetarian Monkeys Have Sharp Predator Teeth" (https://www.youtube.com/watch?v=aC6iYj_EBjY https://www.youtube.com/watch?v=aC6iYj_EBjY) "Geladas are the only primates that are primarily graminivores and grazers – grass blades make up to 90% of their diet. They eat both the blades and the seeds of grasses. When both blades and seeds are available, geladas prefer the seeds. They eat flowers, rhizomes and roots when available,[12][13] using their hands to dig for the latter two. They consume herbs, small plants, fruits, creepers, bushes and thistles.[12][13] Insects can be eaten, but only rarely and only if they can easily be obtained."
