Heat oven to 400F / 204C. Set out a sheet pan and a square baking dish (if making more than 4 servings, use a large rectangular dish).
While oven is heating, heat a nonstick pan with cooking oil (portion for sliders) over medium-high heat. Add mushrooms and saute until tender and golden, 4 to 5 minutes. Add garlic and saute until fragrant, ~1 minute. Remove from heat and season with some salt and pepper.
Set mushrooms aside.
Whisk together oil (portion for carrots and snap peas), garlic powder, salt, and sesame seeds. Toss with carrots and sugar snap peas. Spread out on the sheet pan.
Transfer to the oven and roast, shaking the pan halfway through cooking, until carrots are tender, 10 to 14 minutes.
While vegetables roast, spread the bottom halves of slider buns out in the baking dish. Spread with mayo / mustard dressing. Top each slider with mushrooms, cheese (tear into small pieces to fit on sliders), and then top halves of buns.
Melt butter in the microwave. Stir in poppy seeds (if using) and pour over buns. Cover tightly with foil.
Bake sliders, covered, for 8 minutes.
Remove foil cover and bake until golden brown on top, ~1 minute more.
