Im bored with our dinners. Maybe Im just tired of cooking and meal planning and grocery lists and 4 different grocery stores and my toddler eating very little of everything

Could use some friendly inspiration and tried-and-true recipes. I normally try Marley Spoon when I am in a rut but I have to modify most of their recipes and that makes it even more expensive.
Limitations: no dairy; no non-fish seafood (shrimp, crab, mussels); no avocado. Recipes can have dairy in them as a topping (example tacos) because I can modify but cant be in the main part.
I have our weeks set up with a certain routine:
1. taco dish- tacos, quesadillas, nachos, taco soup, shredded taco chicken fajitas etc (mexican)
2. beef n broccoli or orange chicken or pineapple tofu rice (chinese)
3. burger or steaks or meatloaf or spaghetti squash casserole or pasta spaghetti (beef)
4. bbq chicken, chicken sheet pan, roast chicken (chicken)
5. pork tenderloin/lamb/salmon (random meat)
6. stew or chili or roast (use beans)
7. leftover or breakfast for dinner or takeout
I have been trying to increase our non-meat nights or at least a portion of the main not being meat heavy. Example tofu pineapple rice option or sausage-lentil stew. A lot of vegetarian dishes rely on cheese and that doesnt work for our family.
